Walked through Survival with a Warrior, Summoner, Cleric, Ranger. Get all the "until end of battle" buffs, revives, and war golem. The battle never ends so your buffs stick around forever. Stock up on +power regen items. My Warrior was never even close to dying.
1. Reinforcements needs to be reworked. It's too annoying feeling like I have to click every 10 seconds. How about we just put a rally point down and reinforcements automatically spawn there? 2. The "Attack Range" display when you select a tower is useless and unnecessary considering you can just look at its range. 3. There needs to be a way to check what upgrades I'm using while within the game. These are the only flaws. This is a brilliant game.
No, I promise. God no. Although next week there is a smoke monster... (just kidding)
