Actually I find this alliance event update for tokens very weird. All these while my understanding from the dev for this game was to support more on players who can’t spend whole day playing or towards more casual players. Now the thing is by making this update you will kill the rest of the alliances and maybe only have top 5 alliances left in here. Here are my reasons
Due to limitation of members (60 players) in each alliance most top rank alliances have minimum requirement to join. They will only accept Diamond and above players. You will make gold, silver or bronze players leave this game if they have no new home.
You mention Synergy as an example for good team management. In order to attract another good players you need to have high core level and loyal players. I am one of the first diamond and challenger player in Synergy and before we grow to what we are now, I have resisted the temptation of joining higher rank alliances simply because I believe gathering all the top players in few top alliances is a BAD move for any games. Now with this move you force people like my previous self to join top alliances because of the reward.
We have our sister alliances. We train and help new players to be better at this game in hope that they will stay and keep on playing this game. You just killed our sister alliances because our members will prolly migrate to higher ranking alliances with more active people. If they can’t make it they quit this game.
You cannot and will not be able to have a larger scale alliance versus alliance war in this manner if you only have Royal Guard as no 1 power over the rest because that will make a lot of players leaving this game if they are frustrated in the event. That will kill the game even faster as most of the games I have played before die a natural death with these methods where they create server after server then merge them together once players start leaving the game. Condensing many top players into top alliances is always a bad idea. You need diversity.
Anyway this is only my opinion. The decision is up to you to make. Thank you
