ArenaNet:Guild Wars 2 suggestions/Adjusting weapon style for Different Ranges

Adjusting weapon style for Different Ranges (Discussion)
spears should have melee and range skills. at melee range, the spear should  attack faster but range skills are disabled if attacked by melee. bows and spears should shoot abit further at higher places. bows should shoot further then before and more powerful but cant target anything if being attacked by melee. a person wielding a bow or daggers should move faster because these weapons are lighter. people wielding a sheild should have a chance of blocking melee and range attacks all the time. people attacting with a range weapon should have a chance of being unblockable [eg a stray hit] and all weapons and some spells should have some chance of missing. staffs have a chance of blocking melee and if the your target is at melee range the staff attacks faster. wands makes you cast spells a bit faster than normal and maybe weapons have a small chance of interrupting your foe, if they have a hit and it hits the head armour. and attacking fleeing foes or attacking them in the back have a lot less chance of blocking

 * add a bit more realism
