I have gotten 1500-1600 on every jugg/guardian spec for the last 3 seasons and would definitely consider them weaker than average. I will keep playing it because underdog or lesser appreciated classes are fun to experiment with. It's also interesting see how far you can stretch the boundaries of the metagame. Not sure how I feel about the changes, a lot will come down to if we keep or get a new really good tactical / set bonus to either mitigate damage or can escape reliably (grit teeth, force bound, nimble master are great). Not gonna look too deeply into the PTS changes because we still have no clue how half the classes are gonna play and we need that information to help determine how juggs are gonna perform for 7.0.

If you are solo queing then it's better to play a more self-sustaining class, because jugg without a healer is just miserable. Any rDPS is good, operative or sin too but stealth classes can backfire sometimes as not all teammates respect your role as a node guard/attacker and tend to double up on them which usually just loses the game on the spot unless you have a premade carrying you on the other side of the map. Being a decent stealther should still net you a better win rate than 30% for sure though.

Not unless they keep grit teeth or get a really good tactical / set bonus replacement. My guess is they will return to their 5.0 level or worse where it's something you play for fun but the average winrate will be garbage because you don't have an escape and you will melt in a whitebar. On top of that you will lose a rootbreaker and have to choose between Endure pain or Mad dash so good luck kiting after Enraged defense.
