The problem I had with Glide was never that it was necessarily OP - I was conflicted about its power level. Its problem is that it does the same thing Divine Favor got hate on for years on end - it punishes control decks for just existing, with no real counterplay at all (what, you're going to waste board clears so that they don't Glide them out of your hand?) - but it does it in a way that feels even worse by not just benefiting the aggro player, but by actively taking resources away from the control player when the whole point of the archetype is to have a lot of cards in hand to be able to answer everything. They took one of the worst-feeling cards in the history of Hearthstone and made it feel even worse. The design of Glide is pure garbage, whether it costs 1 mana and is amazing or it costs 10 mana and is the worst card in the game.
Also I want to throw my voice in to say that yes, the meta is currently completely wrong for Glide. I'm not convinced it'd be all that OP even in a control-heavy meta, but pointing out an anti-control card sees no play in a fast meta as though it's some sort of failure just betrays a lack of understanding of how card power levels work.
