Java Potion wand change(Lucky islands)

I recently started playing lucky islands, and there is one of all the wands that I see is basically useless, that wand would be the potion wand. Basically it is not worth it to use it since you do not know if it will have a good or bad potion effect when thrown at it. For example if you throw a potion at an enemy it can be a regeneration or slow potion.Keeping that in mind, it is a wand that I barely use since, as I said before, it is useless. But simply by making a small change, like the wand having two modes, one of them would be the attack mode , which would have the following potion effects: Slowness ,Mining,Fatigue,Nausea,Blindness,Weakness,Poison and Wither.And the other mode would be defense mode which would have the following potion effects: Speed, Haste, Strength, Instant Health, Regeneration, Resistance and Fire Resistance.

And simply by left clicking with the wand the mode would be changed, I think that with this small change it would make this wand more usefull.



For the people who vote I would like you to give the reasons why you think this should not be implemented on the server or what changes you would make.
