Rammus Q

Yea its not colliding with jungle creeps and enemy champions properly, When i active Rammus Q and charge in trying to gank a lane it stops like just inches short of the enemy so it doesn't collide like there's an invisible wall around them that cause rammus to stop just short of being able to hit them, and i have noticed enemy's tower diving i target them with my taunt since there right next to me and they leap away just flat out ignoring the fact that i hit them with a taunt, so i feel rammus needs to be looked at cause his abilities seem to be broken and are not working properly.
