I'm not sure it's been thought about. It might impact significantly on the rotating game mode queue popularity if there's always URF active, plus that's probably too hamfisted of an approach. I can pass the idea on, but I don't think it'll happen. Training/sandbox will be a feature we actually implement into the game, not just keep URF as a custom as a weird substitute, I think.
current offer is nothing now and nothing for the forseeable future, so i'll settle for weird substitute for the time being, i'm sure all the people that care about it would too
other things:
- urf popularity as a mode. idk about this, rito probably has better statistics than me but i'm willing to bet the % of people that even know there's a custom game browser is pretty small
- maybe this'll create bad situations cos you can't differentiate between actual urf and people using it as training mode. you could make it so it's local only, that way you solve this and the above in one move
- maybe this leads to a lot of ppl joining custom games to play urf and they find themselves in a bronze v diamond matchup. yea, again, make it local
- maybe this creates additional strains to rito servers. for the love of god make it local
- too hamfisted. yeah, but who cares. it's better than nothing, and it's exactly what ppl need. even if it breaks sometimes and if it's bad in some respects it's better than nothing
- changes would have to be made for this to be useful. honestly the only thing needed out of urf mode for this is the cdr. the rest would hurt sandbox mode cos you'd be walking at higher movespeed than in the real game and so on. if they just kept the cdr that'd be super. zero costs for all items would be very nice too
- some champions would be broken. i'm sure some champions won't work properly with 90% cdr cos urf had a lot of special case stuff. yeah, probably. but it can be a staggered release if they want, just 20 champions each patch or whatever.
- more reddit whining/support. yeah, a lot of people aren't gonna pay attention to the HIGHLY UNSTABLE message on the loading screen or whatever. unfortunately that's the cost you gotta pay for not making a sandbox mode for realsies
