Free champs in ranked?
So i just noticed that free champs weren't able to pick in ranked which is understandable but frustrating, like lets say somebody practices Thresh alot and gets good with them but cant play them in ranked due to not owning him and doesn't have the ip or rp to buy him(especially for a fresh 30 because they'd be focused on trying to finish their rune page, which costs nearly 8400-18000 ip buying all tier 3 runes from scratch) so then it might force somebody to have to pick a champion they haven't practiced with because the one they've invested most of their time into cant be chosen.
so idk if its a bug and if not, when it was implemented. Just looking for some input as to other opinions on this and maybe as to why it might've been done besides keeping inexperienced players picking something they arent comfortable with(can also be seen in the opposite direction as noted before)
