How do you actually hit Nunu 2 when going fast 9?
So I recently hit Grandmaster on EUW but I really struggle to climb further in this meta. Arguable the strongest late-game boards consist of Nunu 2 with either vex graves, vex bard or bard sona.
When you hit an early winstreak and reach 4-1 with level 8, 50g+ and full hp usually the play should be to not roll at all and tank stage 4. At least that's what most pros recommend, if I understood correctly. What happened to me the last few times I had that exact spot was that every 4 cost tank is almost completly gone from the pool by the time I level to 9. 2 people play Rammus 2 Mighty Mech 2, 2 people play Nunu 2 and 2 people play TK 2.
I don't greed for Nunu 2, I would be fine flexing a slightly weaker board using any other 4 cost tank but it's just not possible. Ultimately I end up in a spot where 7 people are in the game at 5-1, 6 of them are lethal - and I go 6th. It's extremly frustrating because I feel like I could just play a 4cost reroll strat instead and it would be better.
Is the solution really playing arround something like illaoi 2 and hoping for enough other players to drop out so you can hit a 2 star 4 cost? I can't roll on level 8 or else I will never be able to go level 9... I would appreciate advice on this. I hope I don't sound mean saying this but please don't give advice if you're not at least diamond, the game simply doesn't work the same way in lower elo. Thanks a lot.
ps: This is my first reddit post, so sorry in advance if I screwed up some rule about formatting and such...
