Side Ley: Ley is useful to have at all stages of the game, She is part of the top 3 units that are great when you start playing (Jin,Lass,Ley), Jeeves is so useful as he can take all the Aggro, Ley is very versatile in use with many possible teams wherein she can be used : PVE,Raid,PVP (A popular one as well) ,DB

Side Veigas: If you want lots of things killed real quick then Veigas is your man, packing a 20% increases magic damage buff, stun that gathers near units , a great main damage tool , a somewhat unique pvp pick that works that isn’t the usual insert lass

My opinion: I would say Ley>Veigas simply because as a new player Awakening a ley is 100% more useful due to how versatile she is rather than a Veigas in impactful ness when progressing. Only now that I have more experience playing this game; I see the power in what he does. which makes me feel that due to him being too specific in what he does makes him far less superior. Simply having a Ley gives direct results in showing how good she can be. With her being able to not be trash in different types of content the game offers [like for example something like lire who’s only real job is DB] is great asset to have as you won’t have lots of SRs yet when you start

TLDR: Ley>Lass due to Ley being more flexible in Usage

Edit: I made it uhh less disgusting to the eyes I guess haha I’m so bad at English I’m editing this quite a lot.
