One more question, now about sets

Are there any bonuses for having full sets at levels lower then 50? For example i have level 28 dex archer, should i try to get penguin, king frost items or it doesnt matter? Also some items at level 30 have worse stats then lower level items, for example i have level 28 bow with 60 dmg and 0,6 attack speed and i have never seen a single better weapon at level 30, even pink crossbows (which should have higher damage and lower dps) have lower damage then this bow, how does it work? Why are these crossbows more expensive then my bow? I bought it for 2k gold and a pink weapon with worse stats costs 200k gold, wtf?

There are 3 dex sets that are for a level 25, they are dropped in Sandstone caves:

Crystalline Dagger Set:
Items: Jewel Thief's Crystalline Hat, Jewel Thief's Crystalline Leather, Jewel Thief's Crystalline Dagger, Jewel Thief's Crystalline Wing
Set bonus: +1 Damage, +3 Armor

Crystalline Bow Set :
Items: Jewel Thief's Crystalline Hat, Jewel Thief's Crystalline Leather, Jewel Thief's Crystalline Bow
Set bonus:+3 Damage, +1 Armor

Earthquake Set:
Items: Jewel Thief's Earthquake Hat, Jewel Thief's Earthquake Jacket, Jewel Thief's Earthquake Dagger, Jewel Thief's Earthquake Wing
Set bonus: +4 Armor

Only level 35 dex set, dropped in Ancient swamps/Croc feud:

Swamp Rat Set:
Items: Swamp Rat's Dead-Eye Derby, Swamp Rat's Croc Scale Leather, Swamp Rat's Swampy Shiv, Swamp Rat's Blackbird Wing
Set bonus: +5% Crit, +5 Damage, +5 Armor

If you browse pink list by yanis in traders Market, you can see all se bonus there. There is set bonus on all 25 sandstone caves items. Also 35 items have set bonus. Also items rarity sometimes make price sky high, not stats itself.

Thanks folks! I will try to get swamp rats set now :P! or do you have any other suggestions for 30~ full dex avian? At the moment i have pink Sniper's penguin snowcap 7 dex 5% hit 2% crit 1h/s 1 m/s 8 armor, green frozen bow of excitability 50-60 dmg, 0.7 % speed 5 dex 2% hit 1 armor, green assassin's frosty leathers 3 dex 2% hit 1% crit 16 armor.

I also have upgraded items from upgraded start for 30 platinum, 22k gold and alot of random pink items because im trying to be a merchant :p
