Have a generic stamina and magic gap closer;
The double activation from the crossbow skill is wonky, unreliable, and to be honest just plain broken.
I can literally activate the skill charge a full bow heavy attack and use the skill again and have it activate the gap closing mechanic. Which I reported in test when the change was first out on test.
There are weapons DW, Bow, and both varieties of staffs that do not have gap closers as well as some classes that have magic based gap closers but not stamina gap closer and one that has both.
And while I understand and appreciate creating an environment where classes and weapons play differently I also believe every class and combination should have access to such an important utility ability as gap closing.
If you wanted to play a stamina DW and Bow Templar you should be able have access to a working gap closer skill for PVP or PVE when needed.
