So when is AST getting nerfed in Frontline

[Scintilla]

All you can do is turn down non personal FXs, and open your eyes for DRG LBs coming from miles ahead.

An example of one premade we get:
A WAR and DRK will jump into the group simultaneously. The WAR stunning the group, the DRK voking. If caught unawares, purify would remove the stuns, and then you can use Guard. However, by this time, the DRGs of the premade team have already used their LB. At best, chances are you'll have taken at least the first one as full damage before even getting the chance to use Guard. Your HP will be low and Guard isn't enough to cover the remaining LBs from the premade.

Sometimes you can avoid it by keeping away from the group, though, this is almost impossible on some maps. Marking the premade will make them easier to spot, giving you more notice to prepare Guard to avoid both the stun and reduce damage somewhat. But, even if you're lucky and able to use Guard immediately, it still isn't always enough to cover the huge wave of coordinated damage you're about to get.
Not only this, but it requires players to be prepared of the premade's method of attack which, if they only play occasionally, they're unlikely to be.

It's not like people are complaining about one or two DRGs. Then I would understand your advice of "Open your eyes".

Removing premades will just make the game worse and not actually address any balancing issues at all. It's not like removing them will automatically make those jobs balanced, all you'd do is remove the ability to play with friends in a MMO and make the game worse, while still letting the actual problem exist.

There is job imbalance, yes. But there is an immense difference between playing vs teams of randoms and a premade. A good premade is coordinated, attacks are pre-prepared and simultaneous, all aimed at the same target group. Very heavy, concentrated damage on a pre-positioned group of victims. Repeatedly.
Regardless of how well they try to coordinate, a random team's attacks will be a little more spaced. There will be slight delays, giving target players the opportunity to change position, heal, or defend. Any 'simultaneous' attacks will be by chance and unlikely to be repeated consistently throughout a game

If the problem was purely job imbalance, you would see no difference between playing a random team and a premade one. In reality, the difference is a gaping chasm
