Adding new gamemodes... Maybe, but first fix the bugginess of the latest patches.
Improving existing gamemodes (Battle, Siege, DTV, Rageball...) what kind of improvements?
Improving Strategus battles, commented in the thread for possible changes there, but if it means capping respawn rate... no. Period. Thats what you stand on their flags for.
Changing/improving reward (XP/gold) system... not again. I've played for a long while now and its grindy enough. Used to be fast paced fun in leveling. Now... eh. Grindy.
Changing/improving upkeep system. If it means more costs to the player. No.
Working on item balance. NO>NO>NO. Pointless items have been "balanced" so that they are no longer fun or worth using. PLEASE no more of this...
Adding more depth to combat (new mechanics, stamina...) NO STAMINA. We run slow enough as is already. Just fix the broken blocks, stabs and swings that the latest patches have messed up. Don't mess the mechanics over... please. Thats what is diff about this game and why people like it.
Improving graphics (models, textures...). Eh. Not an issue.
Bug fixing/polishing (voice chat, interface...) Voice? Thats what TS is for. Interface? Not important. Please add fixing buggy issues caused by patching "balancing" etc. Did I say fixing buggy swings, stabs and blocks? (cough cough)
