What a mess this has become.
You dont need an EM to tell you how to better your character, you should be able to do that yourself. Its PVM, so what do you THINK you need to do? Ill give you some pointers
1. Dexxer? Get an AI Weapon, and make sure you have one for each slayer
2. Learn what slayer type monsters are
3. Hardest hitting weapons? Throwing weapons, AKA, more damage for you to do to a boss. Concerned about mana? Be in wraith form, and make sure you have mana leech
4. Improve your suit
5. A mage? Stable your horse, get those summons out. Make sure you have your slayer books
6. Trouble on your mage? Add taming with a GD, or add SW for Word of Death
7. Want to get points for healing? Heal the pets/players. Fun tip, GD's are tanks, they take ALOT of damage, go ahead and heal the hell out of em. Try to do some damage too
8. Sampires
10. Pay attention
I could go on, but these are all BASIC TIPS, for any PvM encounter in the game. This isnt unique to Events, this is anything. The same pointers can be said for PvP, crafting, or ANYTHING YOU DO in ANY MMO. There is ALWAYS optimal settings or customizations. If you spent less time complaining, and more time learning, youd be better off.
Also, noone has records of who did what as far as damage. Thats all coded in the game itself, its not like the EM's are looking at ever changing spreadsheets. The last system (items on corpses) was abused by scripts that picked up odd items/bags right away (not to mention half the time people could even find the corpse to loot before it got made public). Does the new system have flaws? Yes, but it is the most fair system we have had.
