I don't think that have need to buff scrapper that much.
Scrapper will melt on heavy cc pressure, but most of class will melt on it too.
The problem is our enemy, vindicator/catalyst/untamed /spellbreaker.
If there has no such OP class on match, scrapper feel pretty good.
Juggernaut is the power source forwvw dps scrapper which is only role scrapper can fit on big squad wvw.
No meta build match game play:
