Buffs are only capped at level 3000, whilst the highest level player is well over 3400, I know people who have every buff available in the game, but still have available skill points, I know the HCS are focused on making the app right now, but the game needs a few more buffs.
Maybe introducing some with composing? Like for example a chance of no frags being used when making composing potions the same way Extractor and Inventor buffs work?
Or maybe introducing a pvp buff, like a buff that lets you attack players +/- 1 level above or below you for every 50 levels put into the buff? To increase range by up to +/- 13 levels? (Which I feel will benefit especially the EoCers who need to attack players for their Daily Quests but have a problem with available targets).
Another buff can also be introduced which works like Keen Edge/Smashing Hammer/Shield Wall/Armour Boost but works on HP?
How about taking advantage of all the Hybrid sets that have been introduced to the game this year? Like a buff working like Barricade or Nightmare Visage but instead converting Armour to Defence and vice versa?
Or else more buffs that increase enhancements, such as a buff increasing Master Crafter Enhancement?
I'd love to hear more suggestions for buffs, and I hope that they can be introduced soon to spice up competition!
