There needs to be a way to return the relic quicker. Allies standing around the relic until a meter fills is the best solution, the more allies the faster it returns. The rate should be less than the speed of capping a tower and leave in the current timer if the crystal is left uncontested.
Towers should have a 2 second period where they cannot be contested after being fully acquired, in capture the relic only.
King of the Hill
The first tower should ALWAYS spawn in the middle to avoid the unfairness of the tower appearing right next to one teams spawn.
Points should be awarded for defending and capturing the tower even while it is uncontested.
Team Death Match
Swapping characters or teams while untouched should not kill you and take a point from your teams resevoir. Swapping classes or teams should not count as a death at all, as this will effect players records negatively in the long run also.
Energy regeneration should be based on max energy, so adding customization points into energy would increase your energy regeneration. Maybe around .2 - .5 energy regen per customization point. I think energy will be the way to go for DPS classes regardless of the change but it feels a little unfair that their are no damage increasing options for customization points. Energy best fits the role of increasing damage right now.
Please release a spiritual damage based class next, for obvious reasons.
The energy return on auto attack should be adjusted per class for balance. Shaman should not recieve the same amount of energy they do attacking as they would from healing ally, as this is much easier to do. Assassins and Pathfinder need their energy returns toned down a bit also. This is just my personal opinion but it's a no brainer that all classes having the same energy return despite their differences needs to change.
Edit: I would also like to see a increase in points for damage done and kills, right now it's very difficult for DPS classes to top charts with the Wardens protection and Shaman assisting. I can kill 2 people and do 2.5k damage on a pyro and barely have over 1k points.
Edit 2: After you've blocked a certain amount of times, lets say 3, CC abilities and pyromancer casts need to start going through the block. Right now one block will almost completely negate all CC on you.
