They'll never make you gain more xp party than solo lol. You can kill way faster as a party so the'll not boost xp on top of that. While people keep grinding and buying xp scrolls, seals, hunterkits, consumables PWI makes money. This is also the reason they'll always come up with new reasons to grind.
It's kind of odd to see you, PJ, EP etc. being all so against hunterkits while non of you even grinded to 115+20 on Jainus coz it takes too goddamn long (WITH hunterkits). What makes you think you'll get endgame lvl and pvp ready (which means maxed out stats) here without hunterkits. I really doubt this server will require a few months of grinding, I think the grinding won't stop, ever.
