After playing around with the "new" cat mechanics with and without mastery, I realized how boring cats are; mostly due to the lack of changes and the removal of arp.
As the "new" cat will focus on bleeds even more, I thought about possible mechanics to provide cats with a little twist.
Imagine a mechanic for rip that is similar to deep wounds or righteous vengence:
if rip is reapplied the old rip's remaining damage is added to the new rip and spread over its duration.
To make this not grossly overpowered glyph of shred might have to be changed.
For example: Your shreds bypass xy% of the target's armor if it is affected by your rip.
However, this would lead to Ferocious Bite not being used anymore.
A possible way to make it interesting again could be:
Ferocious Bite - Causes your Rip to turn into Flesh Wound, causing xy% of the rip's remaining damage over 10 seconds plus (100-xy)% + z instantly. (requires rip to be on the target and removes it)
tell me what you think but please refrain trolling.
