Slag Nerf?

[Grizzlis]

So to start with I think everyone loves their slags. I love my slag too ^^.
Buut does anybody noticed changes on the AA? During event my slag panic rate was like 80-85%, now my slag panic rate looks like 50% no more. I recently played vs rogue, we tried idk like 7 fights and only 1 time my slag stunned her. Actualy I am really mad about mine slag cause he is total useless now. Its nerf or what? Later we tried just to stun and gues what.
1. Stun 2.No stun 3. Stun 4. No stun 5. Stun 6. No stun 7. Stun 8. No stun. Is it normal?
Also we were trying 32lv Slag dmg vs 31lv Clyde and 31lv Shadowlurk. Slag had 139dmg in stats and clyde and shadow had 135dmg. All pets were tried at same rogue. I add screenshots.
