So as a summoner main for decades, I have always found the ‘throw’ skill very useful while wielding a wand, because the last thing I want to do as a summoner, is run up to any monster, or a boss, and whack em with my wand.
In the old days, we could put the throw skill in place of “attack” and never have to worry about accidentally walking into a horde of monsters.
In D2R we cannot equip the throw skill while a wand, or any non throw-able is equipped.
My suggestion is either allow player to equip throw while not having a throwing weapon equipped, or add a new skill, labeled something along the lines of ‘Do not attack’, specifically for the function of not moving to monsters you accidentally left click.
