This re-balance has failed for me for the following reasons:
1. Healers have effectively been seriously nerfed by the changes. Health has been exchanged for protection therefore healers are much less viable. If your protection is down and you've healed to full hp, your glass cannons can still be easily one shot. This leads into point 2.
2. In the Arena my 7* characters in gear level 8 feel feeble. Attacks felt ineffective but strangely enough, my level 73 max skill max gear IG-88 was still killed from full HP and protection before getting a full turn meter. Scratching away at an enemy team isn't any fun, especially when you're buffing them with your attacks most of the time. Although EA is aiming to increase strategy by slowing down the game, it now feels tedious and boring as everything feels ineffectual. except Dooku's ability to offense buff his team while neutralizing your attack. My characters aren't terrible either, I run 7* characters with my mains level 73, alts 71~73, all in gear level 8. I'm normally in the top 20~50 range without buying any extra arena attempts. Today, I lost 4/5 of my arena attempts even after trying different teams and character synergies and finished exactly on rank 50.
3. Galactic war, I was looking forward to protection giving me a buffer for my injured characters to try and heal up before getting smoked by the next team of enemies. Instead, the opposite has happened. Your characters will likely have no protection due to their previous fights and be in a terrible position for the next fight unless you're a chain stunning god of RNG. Since the teams you seem to come up against are arena teams, they're not built for longevity and will contain throwaway tanks.
4. Challenges are broken. Ok, I'm doing them. Hell, I'm doing them on auto with click targeting, but seriously, I'm using level 70+ characters in maxed out gear and skills to do it, and still having characters insta-killed by Cad Bane.
5. The main issue is the fact everything PVP-orientated is slow as molasses and tedious; everything PVE-orientated has overpowered enemies.
I hope they reverse the patch and then review the burst damage capabilities of Rey and the pilots. Give the pilots speed at the expense of damage, the rifle users more damage, slower speed. Seriously, why are the pilots and a girl with a metal rod the heavy hitters? Why not the rifle wielders or the people using LIGHTSABERS instead of junked bits of scrap metal? Back on topic, tweak the burst damage down so that between equivalent teams, you're not one-shotting people unless the teams got offense up, the enemy has defense down, and you score a crit.
The changes that've been made this patch are so big the hp and gear re-balance seems to have failed miserably.
