Demonblade Tryndamere is worse than 975 RP tier skins, and worse than some 520 RP tier skins.

Demonblade Tryndamere has a different model, and new particles on his passive and ultimate. That's it. That's much worse than Birdio, who has a unique recall and unique animations on all his abilities. Compared to Infernal Akali / Shadow Evelynn, his visual effects are also worse because both Infernal Akali and Shadow Evelynn have completely different particles and effects, while Demonblade Tryndamere shares W and E assets with base Tryndamere. One could argue that his quotes are different, but the quality of them is very poor due to the lack of characterization behind them. They're just generic "oh I'm possessed and angry" comments. For comparison, Gatekeeper Galio got updated interactions with champions with his VGU. At this point I'd settle for a skin that's 975 RP tier in quality. Just recolor his W and his E at the least because right now he really feels like a ripoff, and no one in their right mind would buy this over Chemtech Tryndamere unless they don't watch Skin Spotlights.
