Alliances with very low taxes to zero taxes do not survive long, alliances with higher tax rate are able to give out grants to build you cities, infrastructure, replenish your nation with resources needed to keep your nation running, rebuild you after each war and each alliance war, and also to build you projects, higher the taxes, higher the incentives given to it's members. Also if you feel it is very hard to communicate because you don't have discord, a simple solution is to download discord and join the server of your alliance and request to be given the correct role. Simple problem requires simple solution. I was in Castle Camelot for few months and believe me i was receiving heaps of grants, everytime i needed something, it was given to me in grants and was never expected to pay it back, i than got discord and joined main camelot where i was put in academy, they built me up even more, trained me up and from there i took the path in raiding and joined Samurai. Good luck joining an alliance with ZERO tax rate or 10-15% tax rate, let's see how they are able to afford to rebuild you after each war, provide you grants to build cities all the way upto C20 and to build multiple projects. Good luck if you can find a super low tax rate alliance. Also if you have a problem with being on a 50/50 tax rate, download discord, request a ticket and ask to be put on a lower tax rate.
