Guild Wars 2

The only weapons I see frequently summoned are ice bows. Are the other ones worth learning?

Dat ice bow 4 though

Earth Shield for Underground Fractal

Fire Axe for Offensive support AoE might-fireblasts (most people dont use this because random party members will pick it up and AA with it which decreases party damage.)

LH is used in glass-canon PvE builds (some people dont like glass builds -me)
Also party members will pick this up leaving the elementalist hanging dry.

So, yes, they are used but their uses are very little comparatively, and the biggest problem is that conjures other than frost bow shouldn’t be shared outside of PvP.
