After playing Tri-Color, I think a remodified version of it would make a great mode. A game called Naruto: Shinobi Striker has a mode (that needs work imo) called Barrier Battles where you have an attacking team and a team defending a giant frog. To summarize that Barrier Battles quickly:
The defending team has to stop the others from lifting the pillars and attacking Gamakichi - defeating an attacker will drop 10 seconds off the timer. The match ends if the timer runs out, or the attacking team beat Gamakichi.
There could be a ranked version of Tri-Color would play similar to that Barrier Battles. Like Tri-color, there would be an attack and defending team placed in the same spawn points they would be in a tricolor match. The attacking and defending teams are selected at random.
The attacking team would have to make it to mid and claim the beacon. Claiming a beacon
DOES NOT summon a sprinkler in this mode. Instead, it counts towards your total goal of 3-4 beacons. The attacking team has to claim the beacon 3-4 times (whichever amount is ideal for balance) to win the mode. If additional balance is needed, you can even force everyone to return to spawn everytime a beacon is claimed unless there is a minute or less left.
The defending team has to defend the beacon spot. Every kill the defending team gets reduces the 5 minute clock by 10s. If further balance is required, the maximum the attacking team can reduce is 120-180s and time can not be reduced if there is only 30-60s remaining.
This is my idea, as I actually enjoyed Tri-color from a competitive aspect and as a person that dislikes Turf Wars. Unfortunately, Tri-color has its own flaws that still needs work so I don't know if my idea could work as a mode.
