Ah ha! Yeah that's the one
Oh, thank you! That sounds great... I was using Google but found it confusing going back and forth whilst trying to stay alive, nice that you can do it in game too.
Oh I see, thank you! Sounds like there were a lot of permanent boosts that I just somehow overlooked then, also some more nuanced boosts like you mentioned with agility heroes

Thanks very much for the Pudge tips by the way, but I don't think I'll play as that character again.
Thank you

I was using the thing in the bottom corner to upgrade (though IMO it wasn't always too clear) but it's great to know I can shift click an item to view it in the shop (and it's upgrades etc)
btw. I always played as Master Yi on LoL, apparently Juggernaught is fairly similar, but from the character select screen there were only 3 guys available... what's the deal with that?
