I have to say s1ndr0me that VIP system on NL2, 5 and 10 is pretty sucky and it is definately something they could improve. But i think as soon as you get to NL25 it starts become useful. Last month i made Silverstar on NL25 SH (BSS) with ease
But on the lower limits dont focus on VIP systems, focus on improving your game, increasing your winrate and moving up the limits rapidly. Once you get to a good level then you can be cocerned with VIP systems and how to get more rakeback and benefits imo
Best Regards and Good luck!
