I too had the same results you hand Mandar with plat & frost. I burnt thro 1500 of both by the time I pmed Kane & asked him to look into it. He informed me it is working as intended. I quit trying.
Info I can share, to help those around me:
1. Not sure why, but the new crafting system has broken the ingot type vs Damage modifier classification.
Example: I used iron to have 100 % Physical Damage, to enhance to whatever I chose later. Instead, I got blends of 10 Fire/10 Cold/30 Energy/50 Physical or 30 Energy/20 Fire/30 Cold/10 Physical. Because of this, you cant enhance the weap properly, thus ruining the chance of a 100% choice in its damage type.
2. I could get Triple Leeches, but NONE with Lower Defense & Spell on hit.
3. NONE of the weapons with just Mana & Life Leech, EVER got a Lower Defense, it was always Lower Attack or Lower Attack & Lower Defense. So the chance of getting a Lower D & A Spell on hit wont happen.
4. When using Toxic, I could get anything I wanted, but its Toxic, I want the Plat roll percentages.
5. Ive burnt thru 5k Plat over the past 2 years & 2k Frost 6 months ago, all are crap compared to what we use to get: One Triple Leech 50s, Lower Defense 50, hit spell 50 Weapon per 100-200 Plats/Frosts, & that was before the GODlike weapons they use to get when Fek made, His could have 6 Lines of pure power.
6. My suits are various combinations, trying to find the sweet spot. I have 500 BS, 400 Arms Lore, 480 Fletching. I adjusted my luck from 2k-4800.
Hopefully, someone will find the above helpful, or someone will help us. It makes me sad to burn through so much & not get 1 ideal weapon. Help us, so we can help feed the server, please?
