my main grips about the raiding (outside the rope jumping feeling) is the curve of difficulty... let's be honest, the curve is totally bad... if thing was becoming harder progressively you will not have this much people stuck to T5. let's be honest the T1-2-4 are not hard in comparaison of the T5.
- T1 have an ending boss with 2 phase, gears and echo can affect it really a lot. cad hit hard but no One Shoot skill, a group can still make up for some mistake and more important you can have different way to finish this fight.
- T2 the ending boss depend of the way you do it, enrage mode, it's mostly a rush at who gonna die first, you or the boss. the normal way, will ask people to think they way depending of them group. and more important to know each skill of the boss.
- T4 it's a question of organization and train people to follow an order to kill monster. here it's more a coordination check.

and there is the trouble... we do arrive to T5 and... blam the difficulty curve skyrocket. the fight do have 5 phase and most of them have One Shoot skill, the arena itself can One Shoot you. we can feel that Yoshida and it teams have done everything they can for offer a very hard encounter for hardcore gamer. but there we get a trouble... this fight is soo much unbalanced in comparaison of the rest of the T1-5 that it feel like it's not at it place. like said by tons of people before... echo and gears will not make you succes more to that fight, but the worst, is if you don't pass this fight you can't advance.

anyway, all i try to say, it's before change them way to create end game content, they must first focus on master the creation of a difficulty curve more balanced. because right now that the real trouble.
