@K_G0sling Barris used to be very good in the initial days, but later with advent of Protection and now Mods, she is losing her charm. There are few issues that make her not so attractive in arena.
1. Barris heals works as she first bring all the toon to a same baseline and then heals up a little. This will work good in condition where, ST Han taunts, entire opposition attacks him, and she brings he back to his glory back. With AOE attack like Anakin/ Lando, there is not going to be that much leveling as everyone will be in low health. Lumi will be much more effective in this case.
2. Adding mods is very trickly, as you have to see how you want to use her. Health mods are very good, more health Barris has, mode she gives to the team. But then she is dam slow and low attack, making your team itself venerable.
3. If you add speed and cric mode, you are going to lose on health, which is her basic purpose.
I think she needs a bit of balancing, getting her basic attack and speed increase. Since she is the only one who can health the team through EP shock.
