One part of the job when you play an hybrid build is to know the strategy for each mob. It's somehow exiting because unlike caster where you put your ass far from the mobs and just spam your skills, here you are constantly in movement (forward or backward), the placement is really important and hybrid builds allow you to hit in any circonstance: melee or distance (but you do more damage with clout).
So I would say: yes, sometimes you can't approach the mobs or the boss and it's quite frustrating. But most of time, mobs are doing frontal AOE, or you can predict few seconds earlier when they will do their big AOE (for example they targetting themself).
You can also speak with your tank, normally if he's not too bad, he knows whether it's risky or not.
About the PMB, I won't participate this time. I already did last time and nothing really changed since 4.0.3 except the statistics (even if I really want the wings
).
Anyway, you can find my old participation (in french) here:

Moreover I find the warden too much bugged since 5.0: the pet is completely drunk, he has high latency and I really don't like it.
Maybe if there is another PMB for 5.0.1, with Warden's overhaul I will have a lot to say
