Your limited ability to get use out of tools is not an argument for why they should remain pruned. Here are some examples to help you out:
Gouging a healer so druid teammate can get a clean Cyclone while leaving stun DRs open to swap on a trinket
Gouge Aura Mastery, Calming Waters, etc
Gouge Warrior --> Berserker Rage --> Shiv dispel --> "Fear the warrior now"
Just to name a few....
This isn't a Rogue it's a boring-ass one dimensional stunbot.
What they've done over the past two expansions is absolute garbage, and anyone who actually enjoys the gaudy, hamfisted, Fisher-Price class fantasy that has nothing to do with the history of the Rogue class AT ALL could still have that option via minor glyphs without forcing this low-brow trash on the rest of us.
