Fun challenge: try to come up with an effective team build for general PvE using 7 heroes, but without some of the OP meta skills that form the backbone of most teams. Your goal is to get Master's reward in Tahnnakai Temple. No consumables (including pcons and DP removal) are allowed - that would make this too easy!
The banned skills are:
PvE-only: "Save Yourselves!", Ebon Battle Standard of Honor, "You Move Like a Dwarf!", Pain Inverter
Monk: Aegis
Necro: Signet of Lost Souls, Putrid Bile, Death Nova, Enfeebling Blood, Mark of Pain, Blood is Power
Mesmer: Power Drain, Unnatural Signet, Cry of Frustration, Energy Surge, Mistrust, Shatter Hex, Wandering Eye, Arcane Conundrum
Rit: Shelter, Splinter Weapon, Signet of Spirits, Protective Was Kaolai, Mend Body and Soul, Life, Flesh of My Flesh
Ele: Ether Renewal
Sin: Death Blossom
Feel free to not adhere too strictly to the rules - if you reeeally want to use one of those skills and you don't think it's too OP, that's fine. Just come up with something that doesn't look like you used a cookie cutter!
