i LOVE this, as a suupport main lol
BUT theres the problem with the validity and honesty of the players.
many times i've queue'd with friends, where we would- to mess with the 5th we're searching for, all queue as a certain role/ lane. sometimes even on accident.
so imagine everyone in a premade, queue'd as support.
someone mentioned earlier about "only bot lane support" but you can crowd- as far as i know, all 5 players in bit lane, with a support role.
How about only awarding this extra IP if you fall under:
Lane- Bottom
Role- Support
Champion- anyone listed under the "support" tab in the store
BUT again, the problem is that you have unconventional supports.
Brand Support WORKS, but is he REALLY a support? no.
Kalista support is DOABLE
Nunu is listed as support, but he's technically a jungler.
Ahri support can definitely be done, but she's a mid laner.
and then what about other special cases?
Heimerdinger is listed as support, but he's not really the best for that, and did you know Blitz is not listed as a support?
the only other thing i can think of is some pathing/ movement recorder that the game does, and reads like,
"oh i see mellophant queue'd as bot lane support, as Braum. he was bot lane for 80% of the game, he must have been the support! lets give X more IP." and, "i see DreamReaper123 queued as bot lane support, Ahri, but was 80% mid lane. he was obviously NOT the support"
seems like a cool idea though.
Also, the game doesnt reward based on stats. everyone on the winning team gets the same amount of base IP. if it rewarded on stats, it could give flexible amounts of IP based on K/D/A. since supports usually have little kills but lots of assists, if could also read it that way "hmm, the KDA was balance in this specific way, guy was obviously support" the problem with THAT though, is when you have those supports [me] who like to KS their ADC if the ADC is either bad, or super BM, so i make sure i get super tanky. for example, when my girlfriend first started playing, she would ADC while i supported, and i always did better, because i was better at the game, at the time. so with this idea, the game could accidentally read the ADC as support, and reward them more IP or something.
i dunno. i like it though.
