Taidha's Gate
Nope. It’s fine. Overall event doesn’t take that long, and honestly, if it’s slow it is usually because there are (a) a lot of players at the event, and (b) not enough of them run bombs, so the gate scales up, but the damage the relatively smaller proportion of players doing explosions rather than killing mobs do takes longer to get through.
Until the boss fails to die because the timer expires, it’s not a problem.
