14 was much too high dontgothere. It actually encouraged hybrids because a pure thrower was no longer obtainable. I personally think 12-13 wpf per pt would be more fair.
What wasn't done fairly was refusing to allow people to redesign their character after the patch. While many people, myself included, had designed their characters to be effective during the January patch, the may patch came around and absolutely destroyed many throwers because of the wpf requirement. Much of the mob-anger towards the dev team could have easily been avoided if they allowed players to respec their now-broken characters to something that worked with the current patch.
Additionally, they overnerfed throwing again.
they implemented 2 changes to throwers
1) Throwing stack size reduced
2) Most throwing weapons now took up 2 slots
Either one of these by themselves would have been fine, but both of them was nearly the final nail in the coffin. The last useable throwing weapon, war darts, was nerfed into oblivion a few days later, but cutting its stack size nearly in half.
I disagree with your moral assumption that getting more players to use melee is a plus. In fact, I think that makes the variety of characters in cRPG very homogenous, which is a very bad thing. Additionally, throwers had a role they needed to fulfill: risky short-ranged unit that was one of the best classes to take out horses. Throwing gets removed, and to no surprise at all, see a MASSIVE influx of cavalry players.
