They are not cheating, but yes it requires you to farm A LOT. I don't have an issue with the speed of which you farm fragments I do however have an issue with the mobs, they hit too hard. Due to that only people with max gear/upgs etc can farm there which is BS. Any player should be able to farm in the max maps if they have descent gears, which isn't the case now. the speed which with you get trans fragments is not an issue for me, not everything should come easy.
I'm not very familliar with the system, I don't nearly farm enough to get 40.000 frags (and the frags I farm i'll sell). I think the trans system isn't very complicated. you need 40k frags, hand them in to get a ''super fragment'' then you use that on your weapon (idk how) and then you get a trans wep with either 1 or 2 sockets, I think it's 100% successrate but you don't know if you'll get 1 or 2 sockets which is the ''luck part''. I can however ask around and put it in my guide althrough I don't think many ''new people or noobs'' will need this info since it's impossible for them to actually get enough fragments to trans a weapon lol.
