The mammoth OD is way over-the-top. Whichever team has the most mammoths in Rugby or Flag battles will win. Maybe change to being affected by mine damage, or just increase the protection significantly, but being indestructible just spoils the game.

Oh no no no. This new update has spoiled the game, esp for the smaller maps like wave. A better way of resolving the issue of uneven battles would be to only allow players to join a team that is losing or obviously either team if scores are even. At the moment too many players only join teams that are winning, meaning the battle becomes even more uneven - and now finishes even earlier because of this update. Lots of players only join the winning team to get the crystals and then leave as soon as the next battle starts. This means that players on the losing team often get less crystals for playing the whole battle than someone who joins with five minutes left on the clock. This is not fair and is so annoying for the players who genuinely want to play the battles for the fun of the game. When you are losing 3-0 with equal team numbers and someone joins the other team, you have no chance of getting back to an even score. And that player then gets more crystals than you just for being a crystal-grabber, not a real team player. Rant over, but please consider my suggestion of only allowing players to join drawing or losing teams.
