change (modification number) sockets, colour of sockets

i play a bow marauder whos lowest stat is dex, still all i need are green sockets (as i only need the minimum dex requirement for the bow). Your idea would make my character impossible to play

why not just make them progress from the lowest percent chance to a higher percent the more you use on an item but make it a small increase so you cant get the best stats too soon but it won't take hundreds upon hundreds of orbs to get what you want

I had armour with a rating of 400 and when I used a jewellers orb on it to add sockets, the armour rating went down to 250. Why would this happen??
