The are not high again, they are higher, but not at the level they were originally,
It was a error, they just fixed the error. We should face it, before they fixed this error there was really no penalty for dying, other than you had to do whatever killed you over again. I was more than willing to stealth my way to a chest solo after a comm run in EV. I would do CtS or EoT solo on any character with stealth. Even when people were looking for healers just because I wanted the loot/credits or didn't want to deal with a PUG. Less likely to do that now.
We should be just be thankful that they took their time fixing this error too. Pretty much made progressing though HM EC, HM TFB and most of NIM EC very painless. Now they just need to up the credits in EC to the same level as TfB.
now they made everything even more painfull for anybody and tanks get hit even worse.
I could imagine the very high costs to be a big reason for people not to tank but to play dps
