I've always preached progression: Moving Oldschool to the future.
Let's stop fearing "over powerful" items. By adding armor and consumables to balance them, we can begin to introduce a new generation of PvM. As is, Oldschool is way too easy. I can solo every single boss in game and multiple times at that. Is it not time to move on? Do not fear the results of PvP, as I said we can add new armors and consumables in the veteran PvM drop tables.
My proposal:
-All Spirit Shields as introduced in the original update. (No nerf.)
-Corporeal Beast pet.
-Dark Energy Core pet.
-Dragon/Draconic Warhammer: may be similar in effect to the Statius Warhammer or a new and unique effect.
-Elite Clue Scrolls
-Tomb of Healing: Offhand book that has a time based effect of converting 1 prayer point to 1-4 hitpoints. (Effect can be improved upon by other player feedback.)
Think of this as opportunity. A game can only be so fun without challenge within its presentation. Nothing at this time makes Runescape challenging, only time consuming. Is it not time to introduce the future? Or should we fear the consequences and bash it every time it is within question?
