It contains my personal view about alliances, I can be not 100% accurate with all of this so you can comment on that if you see some obvious mistake I typed.
TS for still making really good GDP compared to others for a long time. Basically their theme really fits reality.
Grumpy for gathering really fat old people together who are still willing to kicking ass and are competent unlike some other alliances containing only whales who just go inactive due to boredom.
Arrgh for being raiding alliance for ages. No matter what changes to the meta happened they still are the thing and are able to stay in top 50. They are worse to beat than cockroaches, they can survive everything!
Yarr - stable offshore for some alliances. Due to many problems with foreign bank-alliances ending up as scams. This one proven so far and has become superior to others for quite a time. Booty saver for raiders. It's literally PnW version of Swiss Bank in real life. Classic ones:
Guardians - never seen them underperform during war time which is amazing for such a time.
TKR - creating blocs and doing several fa moves which had impact on the game(no matter if you seen them as good or bad ones). Good fighters, overall doing very well to be recognisable by everyone - ads, forum, discord etc. Staying always in top ten in game.
Rose - well, they were beaten in last global war but still it amazes me that they've kept 1st position in rankings. They have Vexz which is very known player in PnW. But even before she came there they were still a thing. It seems funny phrase "roll rose" it's still up to date but they managed to become immortal at this point.
Better ones:(on the way to become classic ones some day)
Immortals and TFP for being in top ten, creating their own sphere, being overall good fighters, and have fine organisation within their alliances, same with politics. ---I know TFP is a an old alliance but never seen them as being relevant as they are today.
Error404 - good performance last war. Borg is still part of them, right? Just making it even greater seeing theme fits their skills.
KT - being like a zombie no matter what, seeking for brains, you can beat them but they always come back. Not a classic raiding alliance I would say imo. They are half standard, half raiding alliance. If they keep like that maybe they become iconic. But they were like other alliances before so it wasn't idea from the start so it needs time before their current playstyle will become iconic. Thalmor radio is a + too.
Aurora - I am biased here but what I would say is being pretty recognisable - being part of new blocs, artworks, ads etc. Decent fighters in the last war.
BK- good to see a good one bk again with old gov - they are funny again(which was their strenght) and are good fighters.
Camelot - creating new bloc, overall ok, their leader is recognisable in PnW which is a good thing. His radio thing is a + too. He is also guest for other radios.
Colt - overall good but they had major reputation issue.
The Commonwealth - despite with loosing their bloc I think they are overall ok. Can't say more but at least I recognise them and they were always in top ten or close to it.
The Order - good performance during last global war. They have very experianced ex-pirate as their leader so it is a good thing. Close to top ten and are recognisable which is a good thing.
Carthago - because they are top ten and have recognisable player Krampus who has RON.
Not that great: one of the reason listed above in the picture. - simply there is still room for improvement to be good one.
Being dumb tier etc:
Alpha - just nuking, no matter what strategy should be implemented, only nuking is a correct one. Aaaand currently very inactive, even in game.
WTF/Farkistan - a bit biased due to war where they just jumped at Grumpy and just nuking them and stealing slots when no one asked them for that.(I was in CoS trying to grab them down). Farkistan struggles in finding a stable bloc.(previous ones were also pretty inactive fa wise)
Soldiers of Liberty - despite being called the most intelligent alliance in The Jonhsons bloc. Leaving Oasis bloc they were reduced to smaller bloc with unexperianced alliances. They agreed to make Dave III as their representative bloc wise which we all know how it ended up. They could lead the bloc but they chose to be just a follower. They had a lot of experiance from Oasis bloc which they could use in their own bloc but it seems they did not.
TLE - how they discused in their bloc channel(leaks), making whole bloc disband. This is amazing achievement. Leaks are inevitable but what is even worse in this particular example no one wanted to stay with them(oh, even fight alongside with them!) They are only with Federation rn, it makes their future even more darker.
Sorry for mistakes etc. Hope it was somehow interesting to read.
