Just a few ideas, let me know what you think.
1. Remove all but one barrack of each type now that the new training system is here.
2. Refund a % of elixir used to upgrade and buy the barracks that were removed.
3. Add another defensive building or trap. I was thinking like a freeze bomb or something that immobilizes troops or slows them down for a short time.
4. Buffing loons.(HP)
5. Buffing lava hound. (DPS)
6. minor archer hp buffs
These are just some things I've considered in my own time with some speculation. If these things have already been brought up then pardon me (I'm new). But please feel free to comment what you guys think I'm open for anything and if you have anything you want to add to the list please do but explain a bit why.
