I don't know if you or anybody else has seen that if you hover the cursor over your power slot,another power slot will emerge.Just a thought. And high level cap isn't really what Destiny is going for.They have stated publicly (Lars Bakken i think) that like so many other mmo's,you leave the game a week and all of your friends has leveled up to the point were you and them are not gonna share the same awesome experience (mob's getting to strong,they get better loot etc etc) and you are also gonna die alot.ALOT. No fun. So you invest in your powers instead,still being able to give your friends a run for their money even after they have played non-stop for that week.And the gear of course,knowing Bungie,theres gonna be ALOT of GEAR,quote me on that.I have a blue Scout Rifle in my inventory with a friggin tripod,can't use it yet but daaaang son,it is sexy!
