As many forums threads in this category suggest their should be a separation between pve and pvp. Battle spirit should do way more things than it does now. Certain skills excel in pve scenarios but are to put simply garbage in pvp vise versa. This could include certain skill not being able be apply more than a certain amount of times on players only in pvp and not in pve, so it would not ruin the other half of the game. Many suggestions like this can be found in the hundreds of threads in this category.
