On the other hand, I do tend to pick champs whose sole mission it is to ensure that teammates survive long enough not to be a complete liability unless they are a few degrees of braindead, perhaps with a side of easy early harass. Sona, Soraka, and occasionally Lulu come to mind (but I can't play Janna or Nami for crap anymore at D5 MMR, at least not optimally).
Seeing as I climbed two tiers in a season, I think it worked out well enough.
I usually do that, but the enemy teamcomp was so dive-heavy and there was no-one else on my team to protect MF that it was basically pointless to play a passive support and just aim for defending.
So I want more aggressive and tried to feed her instead so at least she had a fighting chance to take someone out.
Also this game was extra painful because my main ADC is MF. ADC isn't my main role but MF is my ADC main to the point that she's my highest mastery champion. I'd honestly say I was easily twice as good as that MF. Who was so bad she couldn't even lasthit and just randomly AA'ed creeps constantly. It's one thing to be supporting a trash ADC. It's another thing to be supporting a trash ADC playing your main ADC who you KNOW you could do better on.
Honestly since I have a lot less time and motivation to play league these days I really need to cut down my champion pool and focus on a select few instead of playing 30+ well. Thing is I've played so long playing everything decently that I'm rooted in that. I played so little ranked in S6 that I basically placed Silver after godawful placements and never played enough to get out despite gaining far more LP per win than loss. And I have no idea which champions I'd narrow my pool down to or even really what roles. Since I used to play every role to a standard where I'd at worst not feed [Although my best case was usually getting a couple of kills and a CS lead; not stomping].
Dosen't help that my old main was Jungle Maokai and ever since his mini-rework he's been a LOT worse in the jungle due to a shorter range on his snare.
I mean I could try and play Bard; Leona; Vel'Koz; Lulu; Morgana; Janna; Sona; Alistar; Taric; Hecarim; Zac; Vi; Jarvan; Maokai; Malphite; Cho'Gath; Rumble; Irelia; Jax; Kennen; Singed; Karthus; Ahri; Lissandra; Miss Fortune; Sivir; Ashe; Ezreal; Corki; Pantheon; Kayle; Diana; Kassadin; Galio; Evelynn; Urgot; Kog'Maw; Lux; Garen; Nasus; Fiora; Sejuani; Amumu; Nunu; Olaf; Udyr; Viktor; Caitlyn; Sion; Kah'Zix; Shen; Varus; Karma; Swain and Nocturne to a Gold level standard...
But I'd probobly not play to a Gold level anymore with a champion pool that deep. Hell; in reality I'd only really need to know 3 roles tops now. Since Autofill would always be Support. 2 roles if I opt for X+Support. [I wouldn't do Support+X since I'd get Support literally every game]
My champion pool is so deep that even with the length of time mastery's been out I have 1 champion at Lv 4 [MF] and 7 at 3 [Janna; Jarvan; Pantheon; Caitlyn; Sona; Sivir; Ezreal. ADC's all being 3's due to me playing a comparatively small pool of those]
I really need to distill my champion pool at this point. But I have a hard time doing so because whenever I do so my head says 'Hey this game's great for *champion* and you play it! DO IT'
