Blasters are really my favorite archetype, that's why I want to give you my opinion about this.
I really don't think blaster's role is "range damage", but I see it as "fast damage". I've never done a blapper, though, but even with my main (Fire/energy with boost range, my only melee attacks are brawl and power thrust) I'll never respec to become a hovering sniper (and I agree that in that case, range would be defense against not flying mobs).
I mean, build up (10s duration), aim(10s duration), 32 nuke (Inferno, nova...) draining all our end, the worst def/res of all AT... All of this is saying me : 1 shot them or you'll be 1 shotted !
And that's why I love blasters

It's not boring at all when you're playing it. You can't start to fight, set the auto-attack and go to get a coffee... And in my opinion it's because my fights are really short, not because I have range.
