As said in this thread, unfortunately Clown / Gypsy requires a lot of gear to be played on "equal" levels with the primary PvP classes.
I've been playing Clown & Gypsy a lot and in a PvP situation while sporting ~100+ STR, I have 2 extra weapons, 2 extra armors, 1 extra cloak, an extra shield, 20+ speed potions, and just around 125 berries. To fight optimally (note, on use of word) this is, well, simply not enough for a class that's more or less limited to one build (two, if you'll just be annoying and get flee/PD as support with Tarot/ and song/dance buffs. Sure, you can have more STR (and have lower HP or damage), have more DEX (and carry way less berries or less HP), or or, wait, give them a shot at the weight capacity.
It wouldn't be so bad, even Scholars now with high MATK have like 250k+ HP (on 1 Tao), Stalkers who opt to use the Magic Dagger for a BB build on a STR stat build would get ~66 more berries, on top of being able to carry ~200 already, and the 50% (supposedly) HP boost for them on Tao (on top of the 10% on the dagger too), Snipers tanking Asura on a bow, point being, we're in the experimenting phase so why not give it a chance too.
