Any many would argue how you "feel" is meaningless when it comes to balance.
Take some time and do some tests, gather data, present it that way. Just saying "I feel this" doesn't get much support.
For example, you can get to lvl 80 and equip same ilvl gearsets on tanks and DPS and do some 500 potency attacks (or whatever) and compare the damage. Then you can make a judgement on Tank scaling and comment on that.
