Some people may find it not to their liking and that's fine. Many have been critical of ThunderWalker because of the introduction of new runes and weapons. Depends on how you define balance. It's a different style of play and such. Balance in our game can't really be noticed until after you have become used to the game play.
Balance is one of our great obsessions.
Our mods change almost constantly to meet the demands of balance. Let's face it the primary complaint on balance is the sniper rifle. I at first did not want the sniper rifle in the game because I did not like the idea of it at all. Fezzik finally wore me down, but I insisted that it be hard to use. We have spent a lot of time balancing that weapon.
