We need a solution to having multiple characters gain 100% and then using RNG to determine who goes next. This is simply not fair, it ruins character's kits like Vader, Tarkin, Thrawn, who are supposed to take back to back turns by design.
It also promotes chaos and luck over skill. I'm pretty sure there is an easy fix which makes me wonder why it hasn't been addressed, especially now with RJT and zPalpatine all over arena.
It makes sense to not allow TM gain to interfere with characters who are taking their turns. First of all no character should reach 100% unless it's their turn or they have been actively gifted turn meter by their ally who's turn is taking place. Abilities that give 100% like Thrawn's for example, will not be hindered.
Make all characters cap at 99% TM while someone else is having their turn. After their turn is over then allow ties to be determined by highest speed. If there are still ties due to equal speeds then and only then let RNG decide.
This change will greatly benefit all players and make arena alot less frustrating and more skill based. We really need this!
