Old Trundle: Lore that didn't tie into anything, and was a full-circle plot in itself. He had no coherent reason for being able to do the things he did, and their effects made no sense (why did Pillar of Filth slow?). All of this on top of a really poor character model that looked plain disgusting.

New Trundle: Lore that actual works with the rest of the League and can be expanded upon at a will. His abilities now fit his new persona as the troll king, and their effects now make sense (ice slows, unlike garbage). The model, albeit arguably strange, is much better than the old one. His new basic skin is great, the classic skin is okay, junkyard is great, and little slugger is IMO, subpar, but some people seem to like it.

Overall, they changed nothing about his kit. He still does the same things (they removed the slow that they were adding on his Q) but made him better conceptually and aesthetically. In my opinion, this is one of the more quality works Riot has done as of late.
