Ivern use to be able to get from Krugs to red with his Q, but since the 2 Cinderlings got removed a long time ago he can't hit them. I honestly feel like if his Q got a range increase of maybe 50 he would be able to get to red from Krugs.
Currently I have found that as Ivern Krugs do get ignored if you start at red buff because they are just so inconvenient to get. And throughout the game they just feel like a pain to get, this makes you miss out on gold which isn't the biggest deal for Ivern since he does tend to buy support items and they are cheaper. However it would still be a nice QoL buff to our tree friend.
