There are two distinct differences between what happened in HW -> SB and SB to SHB. The difference is that in HW, the complaints were coming more from Healer mains more. In SB, the complaints according to Yoshi P, sounded more from people outside of the role. It was undoubtedly their attempt to mitigate the Healer shortage in PF as after cross-world came into the mix, it became a lot more present that Healers were massively missing. If you see the problem of "wow, we need alot more healers in PF" and the feedback you are getting from non-healers are "hey, we'd like to heal but the barrier is a bit too much" and the feedback you are getting from some healer mains from PF are like "Hey I don't like to play shield healer, I'll just stick to WHM or AST, then the logical conclusion to all of that is to lower the barrier of entry for the Healer role. I think at the time, it was probably the best overall decision as whoever was playing the job, was already playing it, so that's that and clearly from SHB to EW, they didn't make any major changes to the toolkit on healers meaning that they both:
- Saw the numbers ticked up enough so they were content with it and didn't feel they needed to do anything else.
- Numbers held on enough that it didn't regress all the way back to SB levels.
