Hey I saw your tweet! I'll try to answer best I can. Some of your questions are things that are still being worked on.
"1. Will he be keeping his weapon? I feel like the club fills a role of "Brutal Melee" you don't see on most of the other league champions and (artistically)is supposed to be symbolic of his power. Will we see the same or a similar version of the weapon on the rework? "
Yes He still has a big club.
"2. Will he still be likable, even if he's a deebo troll. Trundle has good personality, even if it's shadowed by his ugliness. I think that is something strong that draws people to actually play trundle. He's got a **** life, but he's trying to be upbeat and people can connect with that. Will his lore be getting reworked as well with his face-lift(get it)? I think he fits, thematically, within a neat archetype of scarred hero. At the very least I'd hate to see him go from Hero of his village to "gross troll monster". He needs character, imo."
This is something we are still working on, the lore team has lots of ideas for him that are still in progress. I think no matter what he's still gonna have character.
'3. Will we be seeing anything major in his abilities being changes(outside of aesthetics) that you can speak on? If there was one thing about his abilities you could change, what would it be? For me personally, I think he'd be a much higher pick if his ult also applied a small slow or something, just for that added effect of it BEING an ult, but that's just me. I understand he has "hidden" power, but I still feel he's in need of buffing and could understand you wanting to wait until his uplift to get it going. "
I don't know about the specific levers that are being pulled. I know the look of his abilities are getting some polish, but as to the specific stats or numbers or whatever Feral Pony should be able to talk about it more than I can.
"4. How are you planning on adapting his skins to his new look? Are they going to be one-for-one adaptations or are you looking at doing new skins that, if you already owned a trundle skin, you'd be given access to, or a refund of RP if you didn't like the new ones?"
This is a bit more complex. His skins have been refitted to the new look. How we implement the changes is still to be determined. I will say it's safe to expect messaging on this particular subject later.
