Yeh I like this idea with the towers giving buffs/debuffs to the teams when you destroy them and it could probably be added as a Deathmatch mode, possibly BoA too.
I wonder how it should work if a tower is being attacked by both teams. If it should be given to the team that does the most damage or the last hit or something.
I would like to do something with player stats, normalise them in some way, but I'm not sure how I feel about it. I know in some games they recently changed their battlefield systems so that players only get a tiny portion of the stats from their items but it feels a bit unfair to those people that worked hard to earn their items - it also kills the need to earn points for battlefield items as they would be of no use anyway, so I'm not sure it's a good idea for this game. Maybe just for a specific battlefield, but not all of them.
As I mentioned in some other post, I think maybe some kind of ban system could work where each team can vote to ban something on the other team, like mounts, or transformations, potions, or possibly even a reduction to a certain stat, like reduce defense, or evasion, healing, attack etc. etc.
