the new trial is too hard

Look
we're not all gamer master game wizards here
some of us are regular folk

so don't preach to me about gamer culture of today like some guy up there said

im not a gamer
i just love games a lot and love this game to pieces

You don't have to be a "game master game wizard" to follow extremely simple roles.

Tanks: Drag adds under boss.
Healers: Heal.
2 DPS: Shoot cannon at adds under boss. Snare boss when it is in range. Shoot barrels when boss is in range.
1 DPS: Fire dragonkiller when the notification indicating the boss has been snared pops up.
1 DPS: Hit the boss the whole time.

Now, explain to me which part is difficult?
