I don't want to be a jerk-wad, but I'm going to be anyway. I believe everyone has their own way of playing the game, the only helpful thing I would get out of this is the charging shots, which not many people know, nor many people use.
I honestly only use the charged shots only for the orbs.
I barely ever use walls unless I need to get out of somewhere real quickly, this thing only being handy when you're still in Home Waters or in the beginning Part of Open waters, seeing the rest of the game usually has dangers near the walls, and the speed that you get from boosting from walls makes you less accurate.
I also would give the people another option, if they don't like fighting, the best thing to do is swim around as normal Naija with the shield on 24/7.
