Yeah but Thomek were you picking your targets, going for wounded guys and people in light armour?
Against cans and horses they don't really do so much and like you say you are hybrid, when you run out of jarids you still pack a mw katana and the skills to use it, a dedicated thrower on the other hand will have 6 jarids, a 0 slot hammer and no stats to make that hammer any better.
You are right though that hybrid thrower is still pretty viable, which is almost funny considering that all these changes were made to stop hybrid throwers and all they did was destroy dedicated throwing and dent hybrids a little.
Assuming you don't take heavy armour so get hit by a wpf penalty, which as a ninja you certainly wouldn't, you can still take 5 or 6 points of PT, and the prof to use it even though you are main 2hander, or main 1h/shield.
I've seen a number of comments that these changes were mainly made to stop people with high level shields and really hard hitting throwing axes but as long as you wear medium/light armour you can still pack a good 1 slot shield, a good 1h weapon and 4 throwing axes that still hit pretty hard, and the stats to be pretty effective at all of them.
Rather so while dedicate throwers have a little bit more ammo they have no shield and are then left totally naked after losing their ammo, while these hybrids can still wade into the melee or protect themselves if they get targeted for being close enough to make a throw.
So not only did they totally murder dedicated throwing, but the changes failed to actually stop hybrid throwers, they weakened them a lot yes but they are still pretty effective and worse still far FAR better than dedicated throwing.
I just hope the devs don't read these last few posts and see it as a reason to depower throwing even more across the board rather than actually admitting they made a terrible mistake and need to actually focus on changes which reduce hybrid throwers WITHOUT destroying dedicated.
