My understanding of a 'glitch' is that the item or feature (in this case a pet with certain skills) is not working as it once did (in this case prior to a patch).
Technically - Incorrect.
A Glitch or Bug is something that does not function as Intended by its Maker.
Whether or not it is personally inconvenient to someone is irrelevant to the point of whether or not the action is working correctly.
It was not just the Panda that was fixed. The 10 "Training Recovery" skills were Fixed.
Training Recovery adds 10 points at level 1 of the skill, 30 Points at level 2, and 70 points at level 3 of the skill, to the Base HP "Tick" Amount.
The "Tick Amount" is the amount of HP the pet Naturally recovers without any influence from the player by buffs or skills or other affects.
The "Tick" Occurs approximately every 20 seconds, bought the same as we do.
Why not informed? You have been, just now. You Technically do not have to be informed of anything when Bugs are fixed. It's just nice to be informed so people dont "rage" about it.
Training Recovery, the P2 Passive Skill is not bugged nor glitched on a standard error free client.
We are build a table to determine the Base HP Recovery Amount of every pet, and how they are affected by increasing the level to the passive
