I am not JPR but I’ll try to answer.
Depends on which kind of PvP you are talking and what you are trying to do there.
Yes, Kent, Guardians have kind of bad ranged options (damage-wise) comparing to other classes. :)
What do we have to deal damage with?
On scepter (nice 1200 range), “1” has an extremely slow projectile avoidable by simple strafing, “2” is AoE with a pretty small radius, so it’s easy and fast to get out of, “3” is a 2 sec root as well as a vulnerability debuff.
On staff, “1” is a weak short ranged (600) AoE blast, “2” is a very slow moving orb and you need to time (pretty hard to do) and press “2” again to explode it to deal some very weak damage (plus heal).
And that’s it. :) Obviously, Guardian is not a ranged damage dealing machine. :) There are also a couple of medium ranged offhand damage dealing options to help your scepter but nothing major.
Does it affect us in PvP?
In 1 vs 1, not really. Guardian has a lot of ways to get close to the enemy and stay there. It’s going to be very hard to kite a Guardian.
In group vs group, not really. What you do have allows you to do some ranged damage while looking for the opportunity to jump into melee, make a kill and get out.
In sPvP, not really. sPvP zones are pretty compact and very dynamic, which promotes very “in your face” kind of fighting, which Guardian is great at.
In WvW sieges, kind of. You probably won’t be standing under (or on) the walls blasting off at enemies like other classes can. You just won’t do much damage that way at all. But personally, I find that kind of fighting extremely boring and ineffective (for any class) anyway. There is a lot for you to do beside shooting defenders with your “1” and “2” - set up and man siege equipment, hunt for the enemies trying to get into the keep, cut off supplies, kill reinforcements, etc.
Additionally, we can do all kinds of support stuff, damage is not the only thing to do in the game.
In short, pretty weak ranged abilities don’t really affect Guardian much, if you play the class properly. Don’t get me wrong, I wouldn’t say “no” if the devs gifted us with a nice ranged weapon set but even as is I don’t think we desperately need it. And if the devs said “we’ll give you a strong ranged weapon but will have to nerf your survivability or other stuff”, I would say “no, thank you”.
