raiding wise rift is far from similar to wow. How dps specs are played(theres no such a thing as pooling energy in rift), healing meta(too long to explain), tanks(no aoe taunt in wow), raid dps cd management(theres none in wow outside BL while in rift theres several of them), buff debuff managment, support role.the several specs you have to handle in rift compare to the 1 or 2 in wow not to mention that rotations/priority lists are a lot simplier in wow.
Rift mechanics are handle by 3-4 players(thats why most guild sucked balls on zilas) while in wow are handle by the whole raid, raid composition is a lot simplier in wow.Last but not least, power gap in wow is HUGE, gear is absolutely everything 1 boss is hard this week and completely trivial the next with 3 items more while in rift power gap between tiers is 10% at best meaning in wow gear can carry potatoes all the way to china while in rift they wipe for 4 months in the same boss cause gear cant carry potatoes.
Outside of raiding, like every single mmo in the market,its the same shit, farm this farm that, dailies, weeklys, crafting etc etc
Thats coming from a member of the guild that shall not be named that moved from rift to wow.
