most patches are just 1:1 from KR by now (including every bug KR had at patch time, they don't include the fixes they had to make later for that patch), but they go the extra mile to remove the best rewards or increase the stage needed to grind for the western release for whatever reason.bugfixes (even emergency bugfixes) which are a week 1 patch in KR take sometimes up to 4 months to arrive in NA/EU.incredibly incompetent developers, be it performance or bugs (you can clear the highest possible stage with bugs, which is still not fixed).western release has 1:1 the same upgrade costs as KR (while having 10% of their income).gear progression is now RNG as well with an incredibly useless pity meter.from soulshield chests, KR can choose, EU/NA is RNG) western release has now every RNG aspect from KR (and even more f.e.
you grind the dungeon not for any other objective (like raids) but to grind the same dungeon again (which is additionally really unrewarding now as well with RNG class drops, instead of just directly dropping your class as it was previously).no more raids for whatever reason (which made half of my clan quit).In my opinion it's not worth playing anymore.
