The ult is basically a targeted Taliyah ult with less mobility. Plus, you can't flash over the gate, but you can flash over any other terrain, so it's not remotely inescapable. It also does no damage (unlike most other global ults) and has a smaller effective area than an ult like Taliyah's or Gangplank's. It also can't be cast into areas without vision, meaning that if the enemy breaks LoS with your team you can't really do anything either way.
The W got some changes. It's now just beyond melee range (smaller than even a no-charge Galio taunt), meaning that unless the enemy is being super dumb you'll only catch 1-2 dudes at most. You've also got to basically be in the middle of the enemy team to do it. The duration's pretty long, but nowhere near as long as Rammus's, and he doesn't get resistances before he casts it or straight up damage reduction (see Galio, who also does way more damage). Honestly, it could be argued that an Alistar W-Q is just as effective, since it's a stun instead of a taunt.
Glad you enjoyed the submission, though, and thanks for the feedback!
