I'm extremely wary of giving in-game benefits to players who buy CE's. Beta Access, Larger Inventory, Early Access are fantastic. Titles are also good. Mounts (if you still have to pay for them in game, you just get a different horse) are good too. But giving extra inventory space, bank access and shorter cooldowns is getting too close to the pay to win. I want things that don't provide people an unfair advantage because they shelled out an extra $100, otherwise it breaks the game, albeit slightly.
