No, on this I 100% agree with you. I would even add that 3e was WAY WORSE then 4e at high level, because every little circumstance chance caused a recomputation of bonuses, and you kept forgetting about some of them, which then caused backtracks, etc. It was bloody awful, first with 3e, then with Pathfinder when it became as bloated. For me, it also comes from the fact that 4e was designed as very linear in particular because although you gained a few powers, you mostly replaced them, which led to much less inflation of complexity than with 3e where everything was additive and became geometrically more complex because of combinations.
