Strikes is a strange game mode : part of the community find them too easy and cheese them in less than 10min (without FS and CW too long by design) with a 250li/kp raid squad , the other part is a total mess of rainbow gear helped by a few geared player who don't want to create their own raid mode squad.
No vocal is required to access, low or no expectation, no hard fails, cc and therefore no real learning of the game and the class...
Fractals incluing T4 are quite the same, CM have the "hard" CC checks, dps checks and are quite the only non raid content where class knowledge is needed...
All calculations done currently are assuming that we will get enough strike currency to buy max MC and clovers per week, if they keep the rate as low as current strike reward it won't be even close.
Even non CM fractales runners are able to afford a few clovers per week using their t1/t2/t3 or rec relics and their login rewards ,the huge impact of the change is on these people not on the CM people who can afford to buy MC coins from trading post when they need them (and if you bother to check UFE kp.me often you will notice that high ufe = high LI/LD and therefore legendary armor already done or with good progress, backpiece done and shiny legendaries weapons... ).
