Training mode should have more options than the options it has now
I like using training mode to check out champions or skins or try out item combinations or just rush through a game for a little bit of fun but if we're looking at the options that Training Mode offers I'd really like to see a few more than what it has.
Right now there's no option to spawn either Rift Herald or Baron. I can imagine people that like jungle want to (for example) try to see if they, at a specific level with specific items, would be able to solo Baron without having to wait 20 minutes in the Training Ground for it to spawn. There's also no option to level your enemies or even to give them items, which would be nice if you'd want to know how strong you'd be against a champion on higher levels without having to wait for them to farm/kill up to a certain level to test your theories.
I'd really like to see those options added. They might be really niche but it really bothered me a while back that I had to wait for Baron to spawn when I wanted to see how much damage I'd be able to do on it solo. You can already spawn jungle camps, Drakes and even Elder Dragon, adding Herald and Baron sounds like they'd just be missing out on a lot of "fun" IMHO :P
And I understand being able to give enemies items would be pretty hard but being able to level them would already be really nice just so you don't oneshot an enemy the moment you see them but actually can kind of imagine what kind of damage you'd do on an enemy if they'd be higher level.
I'd also really like to see being able to add items to training dummies as you always do flat damage to them and it always seems a little underwhelming when you fight real enemies with items.
They're just suggestions and I don't know how many people use training mode to test out theories, but I'd personally really like to see those small changes, even if it's just adding the Spawn Rift Herald and Spawn Baron into the spawning options :P
