IMO, depends on if you have both AF sublimation pieces.
Sublimation only matches refresh with 1 piece while it is active, but you'll lose out in the 30 second reuse time. At larger events, you'll typically have a refresh, so it isn't even needed after the first use. It's definitely low on priority.
If you do have both AF pieces I would imagine you would be using sublimation significantly more often, so it could easily justify the merits.
I'm sorry.. But I need to completely disagree with your logic here.
Before af head, I can understand taking a refresh for the sake of a higher mp tick. But like it was said, post 60, their are very few times you should ever need to receive it. Their is NO such thing as perfect scenario, so with that said, its highly unlikely that a rdm would be able to keep a perfect refresh cycle with out a gap in between refreshing you. So that 30sec wait is really somewhat irrelevant.
The only times to justifiably take a refresh is because your hp is too low to use sublimation, or you dont have enough mp to SS + sublimation(start) than rest. Otherwise your just wasting a rdm's time and mp when it could be better used elsewhere.
My sublimation max 5/5 gives me a 300~ mp storing ability. So that means rdm would have to cast refresh twice on me just to match that. 80mp... or an ability I can do on my own. Again I'll say it, waste of time and mp. If your rdm's are doing this in your ls it's likely because your sch's suck horrendously.
I will agree though that having both af head and afv2 body help quite a bit. Before you say it though, or someone else does, you would realistically need to keep 1 or both pieces on full time to have it match or beat refresh. Like it was mentioned though, the idea is that Sch is self-sufficient and should be making things easier, not the same old same old that comes with other jobs.
