I do believe we should have more bans. My reasoning is that, currently, 3 bans just doesn't cut it with the way the meta keeps shifting so frequently. Another thing I'd like to add on to this is a touch-up on the point everyone has been making about the increasing champion pool.
Right now, we have over 120+ something champs. Banning a total of 6 (the current 3:3 ban per team) is not enough to cover it. Now, I'm not saying that we should be allowed to ban 80 champs or some outrageous number like that to match the champion pool, no. What I'm saying is that if not 6 bans per side, we should at least be able to have every player on a team have a ban opportunity (i.e. a 5:5 ban per team)
I understand that the ban system was initially meant to ban strategically, like banning sustain champs if using poke comps or banning hard engage/disengage champs if using a burst comp and stuff like that, but right now, that isn't what the bans are being used for. (At least, not in SoloQ)
If anything, (and if at all possible), the bans for LCS/any ranked team queues (i.e. 5 friends vs 5 friends) could remain the same, since communication with teammates is present in these games. [Well...for the most part, anyway.] And then they could switch the SoloQ bans to the 5:5 ban per team thing I mentioned earlier.
Going back to the 120+ champs, again, we currently have about 8+ FoTM/OP champs right now, including but not limited to:
- Permabanned because just....NO!
- Can't decide if op or just FoTM, but most players say he's broken so I listed him
- Ever since Riot God-buffed him, for unknown reasons
- We'll see what happens with the Runick Echoes nerf, but prior to the patch coming up, he's pretty op with all that MoveSpeed/on-hit
- I stopped seeing him, for quite a while after the nerf, but I do still believe he's one of the op champs
As you see here, there are 11 champs that are ban-worthy right now (in SoloQ, that is). Each team gets to ban 3, meaning 6 out of 11 are banned. This leaves the other 5 champs available to be played. That doesn't seem like much but when you consider the ones that are generally banned:
Team 1 - Xin - Mundo - Jax
Team 2 - Zed - Kog'Maw - Jhin
This leaves open Yi (ridiculous damage), Veigar (ridiculous damage; kinda like Nasus, however has his own damn-near 2 second AoE stun), Tahm Kench (god-like peel), Lee Sin (just a pain to deal with in SoloQ, as this champ relishes the lack of communication), Udyr (though slow to start, once he gets his items and Runick Echoes, he can't be killed and does way too much damage, even while building nothing but tank).
TL;DR - We need more bans, because the number of FoTM/OP champs cannot be settled with just a measly three. 5 bans per team seems like a logical and fair fix. LCS and team (5 friends) ranked games can remain at 3.
