As a matter of fact, yes, I've tested every single boss on the PTR. With the exception of Iron Juggernaut and maybe Immerseus (last time I tested it RoP change wasn't implemented) Arcane works fine and is, in fact, stronger than Fire in a few cases.
I can play all 3 specs but I prefer Fire. I have preferred Fire since Wrath even with all the ups and downs. I am saddened to think that Fire is just going to be the movement spec. If we are just that spec that doesn't really do much except freedom on movement intense fights I think that is just horrible design. I get that Fire scaling is out of control but that just means once you get to that certain ilvl you will just take over with your normal rotation and a subpar dps CD. That just sounds horrible for Fire moving forward(unless they actually do something different in 6.0). Just play another spec until you get heroic gear needs to go away.
I just hopped on the ptr to try out things, havent been on since the icicles were implemented. I love the RoP change. That essentially solves all of arcanes problems. So much space to move around in. Not many bad things are that large.
I felt like I was doing more damage with more than the 9k haste breakpoint than i was sitting on it though. Hopefully our gearing allows excess haste.
After testing Immerseus last night as Arcane I really see few issues about it. Juggernaut the main offender at the moment.

"Finally fire nerfs, frost gets nerfed after buffs too. Arcane still unscathed"
I wouldn't say it's better for arcane just because it's the only one we use, because fire mages could pump extra dps out of it being able to scorch within the larger area..
Technically fire and frost can get a lot of benefit out of it as well.
However I do see what you are saying, and it's a complete flaw in design on blizzards part that we're forced to use one talent over another because we wouldn't be viable without it. It's hard to put an actual # on how much it'll increase our dps out-put, and I wouldn't mind a small nerf tbh. If it happens I won't be upset, and I know if it does happen it won't be anything major.
If arcanes damage IS too high, then by all means nerf it. I just wish the fire mages saw nerfs through my eyes. If the damage is too high, then it deserves a nerf, even if it is the spec i'm playing.
The only benefit Fire and Frost would see is the scenario where they don't leave the rune for the entire duration, in which case they get an extra gcd every minute.
Not sure what you mean about Fire Mages being able to pump out extra dps while in the rune. Invocation allows you to scorch anywhere in the whole room within range of the boss. The only benefit as I said, is the extra gcd in a perfect situation.
The difference with Fire nerfs, is they almost always impact actual game play, not just numbers. I don't have a huge problem with this nerf since it will have less impact on how the spec plays than others might have.
a) How much has the nerf really hurt fire. I.E. is it too low now? and
b) With Combustion being our only real "fire" CD, what does this change do to damage the identity of the spec and how it feels to play?
Some other questions might be how Frost is scaling with the new mastery changes (I haven't read much into Frost, I really dis-like it's current play style) and if Arcane may need some minor reductions to keep it in line, since it also scales well and now has had the burden of perfect RoP placement removed.
I don't think either of these questions will be answered fully until the patch is released and the majority of mages here have a chance to raid and experience what Fire is in 5.4 vs. 5.3. But for now we can speculate! And speculate we have
Hows the new frost mastery going to affect us pvp wise, doesn't look very bursty.
Also, re-thinking arcane's burstyness will help on quite a few fights. I know it'll help with immerseus, which'll be a joke anyway...But you can burn adds down quicker.
Same with the third boss, when you go into your own realm it's multiple mobs. Fire needs a build up where as arcane can just blow it up. So just thinking off the first few fights it'll be helpful but not a must.
I think a few other bosses it may help too, will need to re-look at a few.
