Is this anywhere ready for CLS

Don't NEED a zeta for the event but r2s number crunch is a good zeta, need more speed on your characters though

Gear and level are fine, you just need SO much speed

Should be fine gear-wise. You should not need to zeta R2 for the event, unless you run him in arena now, then of course do it. You're more than adequate for OB, Leia and R2. I had Han at G9 as well and had to move Luke there mid event, but it can be done with what you have with good mods.

You're going to want a ton of protection on STH - those are the two hardest stages IIRC. You will probably need to move arena mods onto Farmboy as well. Otherwise, you're fine.

Youre fine gear wise and would not "waste" a zeta for this, even though R2's woundlt be a waste. I recommend spending 1-2 weeks only on mod challenges, 3* ofcourse. Literally only spend cantina energy there and youll get some good mods eventually.

I believe R2 always has his event at the same time or just before Luke when Luke’s event is happening. Basically, R2’s event does not necessarily mean Luke’s event is coming, but when Luke’s event comes, R2 will be with him. Same with BB8 and Rey

Give the best modes on them. Gear is fine.

R2 came in May because his character was released on May the 4th. So they celebrated by having him again. I would think this is separate from his regular schedule
