Yes you do have to spend a lot of money if you want to pvp in this game.
after about level 55 there is forced pvp,well it`s pvp if you consider getting killed in 1 hit by players who are 25-30 levels higher than you are,pvp. it`s forced pvp because you can`t level above level 60 unless you pve in a pvp zone that is open to level 80`s of the opposite faction.
I agree with most of your post except this part. You are not forced into a map
. You could very well grind in Jungle, Desert, CS, pando, OI, or even dare I say it, D-water.
The problem is what are you rushing to 80 for? PvP? What will you do once you're at 80? The exact same thing you are saying the other faction is doing.
The exp is not slow nowadays, compared to a year ago the exp is much faster. The grinding is easier and 10x faster. You don't even need to grind, someone else does all the work and you get the exp. I fail to see why VR/PR is the issue. Again is VR/PR the only place to get exp?
To the OP question, best to try this out but don't spend anything until you see the results after a few months.
