Only thing that was buffed in easy dungeons (from HM to SP) is boss HP. (Maybe little too much for my taste.) All other things in easy mode was super nerfed to the point, you don't need do any mechs at all. (Even mechs that wiped party in UE3 was removed.)
HoI, TC and FoE actually have KR easy mode so they are even more easier now than before UE4 update. All easy mode dungeon you can do without doing any mechs so stop spreading lies and false informations. Do some research before you start crying on forum.
Our clan already tested all easy mode dungeons:
ST
1. boss - no mechs. You can kill boss little faster if you share that lightning attack so at least 3 ppl are not frozen during phase and do damage.
2. boss - no mechs.
BC
1. boss - no mechs. Avoid doing mechs at all. If you block orb and stay stuck in that orb aoe, you will die.
2. boss - no mechs. Only avoid stepping on small circles during phase. You will be dancing and die after few seconds.
CC
1. boss - no mechs.
2. boss - no mechs. Just stay under the boss during phase.
SP
boss - no mechs. You don't need kill both bosses in same time anymore.
HoI
1. boss - no mechs. Party wipe after fail mech was removed. Boss HP was reduced. You don't get IK from spiky wall, only damage.
2. boss - no mechs. Party wipe after fail mech was removed. Boss HP was reduced.
TC
1. boss - no mech, no party wipe after failed mech. Boss HP was reduced. Around 15% of boss damage is taken by mech. So if your party is not well geared, mech is still needed because enrage time is only 1m 40s.
2. boss - no mech, no party wipe after failed mech. No damage on debuff when boss jumping. Boss HP was reduced.
FoE
No party wipe on any failed mechs.
2. boss - Try avoid steping on black aoe circles or Master Hong blue aoe areas. It takes huge amount of HP even for well geared players.
In conclusion dungeons from ST to SP should have less HP on bosses in easy mode. It's strange that newer dungeons are more easier and much faster be done than older ones. Other than that I don't see any problem with actual event.
