The assassain tree is easily the best, but don't forget there are other good skills. Fortify, hunter's pursuit, sylvan touch, etc. It took me half the game to figure out you're not limited to one tree lol
Hito, the controls on this game are really streamlined, what are you talking about "sticky"? And it isn't P2p, it simply has a p2p option, like most decent free games
@Nova, you can test decks in the trainer without losing any money. Also, the single player isn't that bad, just get a decent god deck and grind them, every card you win gives you just over 1000 electrum.
Clear, how would you nerf them? Do you want them to do half a point of damage instead of one, just so immortals that are invulnerable to everything else can be even more overpowered? There's a reason they're vulnerable to shields.
