in fact you get all ur tools to have a optimized 80 rotation by lv 50, 58 u get drill which is like fleche and only act as damage, and 66 with stabilizer and everything is is shallow "upgrades"
MCH 4.0 issues with progression is you get skills that dont make sense or useless way too early. While 5.0 busts its load at 50 and barely evolves at all through the 30 levels making it feel hella stale. Your rotation used to be in a single trait at lv 64 now stretched out awkwardly at lv54 lv 60 and lv 64 and i have no clue why they did this Drill could be moved to 60 and the whole rotation be at 64 like in 4.0...and man im digressing again. Yea the job doesnt evolve much from 50 most of its new tools are upgrades
