With the GL's having such high base speed it makes me wonder if there is a cap on speed in the game. Stat caps are a very common mechanic in games that allow you to customize your stats where people min/max because people always find the 1 key stat and build almost exclusively for it, and many devs don't like that so they'll use stat caps or diminishing returns (a soft cap) once you get past a certain point on that stat to prod people into diversifying their stat distribution.
So I was wondering if GL Rey and Kylo have such high base speed in order to put them relatively close to the cap so that people with them would be encouraged to spread out their mod focus instead of just focusing on speed.
I won't be getting either of these GL's, so I'm unable to test myself but if someone wants to test a mirror match with 2 Reys or 2 Kylos both over 500 speed but 1 a good 20+ speed faster than the other, you'd be able to find out if there's a hard cap easy enough if the faster one always goes first, if the start is RNG, then both characters hit a cap. If there's no hard cap, the slower GL can start walking back their speed and seeing if there's more and more of a difference or not proportionately to see if there's a soft cap.
I may ask this in next Q&A as well. Though I doubt my question will get picked and they'll focus on an art question instead.
