I have good base (1k+) and i did damage tests between bof4s and 3slots and it honestly wasnt enough for me to justify. on ls it was either3-4 dmg per tic (15-20 total) on pi mobs and 2 per tic in pvp for the almost 500m difference for 2 of em, really couldn't justify it for that. but im sure as other gear gets completed and there is less and less room to better my gear bracelets will come around.
