i really hope riot doesnt keep adding percentage damage reduction to reworks

reworks are fantastic, however my issue with them is honestly their damage reduction, I get they can be tanky divers but the amount they can get, gets a little silly, warwick with his 55% and galio with his 40%. It can get higher in galio's case, but isn't necessarily ideal unless hes vs an actual ap heavy team. See I get they're meant to dive, but not really be unkillable I suppose. as they can usually kill the target they're after before they go down, if not heavily wound them.
