The controller role seems heavily unbalanced right now to have an idea I'm gonna expose to you the pickrate of each region (taking VLR stage 2 data of 2024) :
For Americas : Omen have 73% pickrate, Viper have 41%, the next smoker after them is brimstone at 12%
In China : Same pickrate (73% and 41%), and the next smoker is astra at 10%
For APAC, Omen pickrate is 77% and viper's 32%, the next smoker is clove at 8%
For EMEA : Omen pickrate is 75% and viper is at 31%, and the next smoker is brimstone at 6%
Across all regions, Omen have a 74.5% (for stage 2), so 3/4 of maps you will see a Omen
(In masters Madrid Omen had a 68% pickrate and over 60% in Shangai)
What can we do with this information ?
We can assume that the "niche" omen and viper fills make all the other controller useless, exemples right there : For Brimstone, why having 3 instant smokes not refreshable when you can have 5 trhoughout a round that allow you to be extremely precise with the placement. For Astra you can only place up to 4 smokes and not place any other utility, and if you place utility, you need to be 5-head to place a good stun, but Omen just look at minimap. For Harbor, you give away your position when smoking while it is not specially bad, when you need to play slow defaults and you only have a single controller harbor, it won't cut it.
I can completely understand for riot to keep Clove to ranked, but the rest (Brimstone, Harbor and Astra) should not have a pickrate that low, I really hope after champions we can see the huge patch that make controller relevant like they did with iso(but not as broken) and neon
Thoguhts ?
