Banners and Weapon Swapping
I have noticed this as well and this is very annoyning.
I hope they remove the cooldown from banners.
Hello everyone,
I am pretty sure it works the way it is supposed to be. Here is a little explanation:
Banners (warrior) and conjured weapons (elementalist) work the same way. They are both environmental weapons (http://wiki.guildwars2.com/wiki/Environmental_weapon). Since conjured weapons trigger sigils, etc. banners will trigger them too.
Besides that it also makes sense. You are switching from your regular weapon (e.g. a hammer) to a banner, frost bow or any other environmental weapon.
I hope this makes sense and helps.
Have a nice day.
