QoL/Clarity Suggestion: Synergy Indicator
To elaborate, I mean a set of icons or something next to each Summoner's username that indicates what synergies they currently have, or at least the option to see them all at once by pressing Tab (similar to checking builds and scores in League itself).
This may sound pretty trivial given the random nature of this mode, but it gives a crucial bit of information: how many teams are building a certain synergy, or rather how much competition there is for that synergy.
Say you are trying to go Ranger. If two or three other teams have Ranger Synergy before you do, it may be best not to do so. Unfortunately the amount of time given each round is not enough to check each individual arena and buy champions and build items and fix positioning.
