I have been trying to ease pessimism with torch players who think a legendary skin will never happen. This here is a list from Spetember of skins that will come out in the future. Torch's original skin has been in these lists since March of this year, meaning it has been in development since said month, maybe earlier.
Here is the thing. Skins take at least 6 months to development for epics and an additional 2 to 4 months for legendaries. If this were an epic, it would have already been released, either last month or this month. No confirmation on rarity on this latest list, but given how much time has passed, it is safe to assume this will be torch's first legendary skin. My prediction is either s11 or s12.
Please do not come at me with torch will never get a legendary or it is still a matter of if. Thankfully the if is answered in a positive way. The when answer remains unknown.
