Ok so, a little food for thought.
The new slots are pretty awesome for precrafts and fusing up to legendary with 1 less items required, therefor, making getting those legos and mythics a little faster, because you don't need to make so many. BUT, if you're doing an EEEEL or ELLLL fuse style they're not so good. It seems to change the odds to something less beneficial, so using a fusion slot that isn't upgraded will still be better in this way.
I'd also like to know, if I do a LLLL+L fuse in this premium fusion slot, and fail, is there atleast a chance that I'll loose the fake item?
imo, if an upgraded slot means you no longer loose your hard earned legendary items that would go a long way. I accept that mythics should be hard to make, but I dropped $40 on this game this week and I'm second guessing that decision, if this new slot meant that, yes, I can obviously still fail the fusion, but I'm no longer going to loose one of the legendary items it took me a week to make.
Please, let this be the case, if not CC, make it so(insert Cpt Picard gif here). You know your customer service has been subpar lately, and you may not notice so much with all the new markets, but you are bleeding whales, we've had atleast 6 high spenders from my city leave the game in the past few months. While parts of this patch were what we wanted, in other ways, you just soured us even more. The premium slots are good, alot of that is just adjusting to the new system, tho I'm sure there are a few people out there who went right out and bought all 4 upgrades then realized how they actually work and regretted it with no way to go back on it. The enchanting leaves alot to be desired. you're asking us to burn already hard to get mythics to make one slightly more powerful with no decrease to risk. This went much longer than I intended I'll leave it there.
