Is what people have been saying on the previous post, it's not that you can't complete this for melee. Is that as melee you need to know to avoid wicked wheel, also there are different tactics that make it easier for a melee heavy group. There are multiple ways of completing this, some are easier than others on melee too.
The problem is generally that melee players are too busy trying to do more damage instead of concerning to move out of the way and dodge abilities. Wicked wheel is dodgable. Tanks can help also with cover. Anyway.
As it was said before, is just those players being bad. (not the ones in the picture)
I was gonna like your comment but damn, it's not true that it's always harder on melee than on range. So off. While some mechanics are easier for range than for melee, it also goes the other way around. Some of these fights are just as easy for both, or harder on one than the other.
No fight in this game makes it impossible for either job. It's just the players playing those jobs.
Is like those idiots saying "Titan is impossible for casters, too much movement! Take melee!" Or then the ones that say "melee sucks on titan, no melee allowed" (there's a thread about this one). Both are just as wrong, Any job can perform well. While some fights may have better affinity to specific jobs, it doesn't mean it renders the others useless. on the contrary, difference is not that noticeable most of the time. (You can complete T4 with only melee btw too, not casters cause well soldiers just can't be killed by casters QQ)
If you gather around good players, you'll notice these are mostly myths or just specific cases that involve less skilled players.
If you chose melee you should be prepared to move to reach your target, just as if you chose to play a caster, be ready to interrupt your spells to dodge enemy attacks. That's just the way it is, think about it more deeply before choosing what class you're gonna play.
(btw this is not a personal attack, just continued from what you said to expand on the myth that it's harder for melee than ranged, different does not imply harder)
