If you don't have the cash to get your own +7s it's simple, put in some work :P
Not really hard to get top end stuff now, farm easy things like ts scrolls, fossils, weapon enchants. Then when you have 100m which should only take a few hours buy low sell high.
The people I see most benefitting from rental is hackers, as for hackers in CZ using IB +8, with all the bans happening recently doubt they're gonna be keeping it too long.
Speaking of which, k2 are doing their job recently watched 100+ get banned last night, a ban every 5 seconds.
Oh and about xtrap being better, it causes more problems than it solves. If they get xtrap there's gonna be hundreds of people who can't play purely 'cause of xtrap problems, is it fair that people are unable to play just 'cause xtrap doesn't like their computer?
