I've now seen two people from Seal Team exploiting the wonderful, classic, item recharging with vendors mechanic to power level.
I've seen a ranger go from low 40's to 50 within a week or so.
Keep in mind that item recharging was disabled on the Red server for these exact reasons.
They are quad kiting specters in OOT on garg island using Red Wood Wands.

I mysteriously noticed two very high level merchants nearby were cleared of their inventory and sure enough, someone from Seal team was on garg island quadding spectres.
All you really need is about 6 or so of these wands.
Each wand casts an INSTANT 76 dmg aoe from an inventory slot with 5 charges.
5 * 5 * 76 = 1900 damage which is plenty to take out a spec.
Run to the nearby merchant to recharge them all for 30-36p and you have plenty of time to run back and stand around until respawns.
Specs drop scythes that sell for 12.5p each along with random gems and research materials which can help cover the cost if not turn a profit with some luck.
Yes it's classic, yes it's cheesy, I honestly don't think anything is going to change, and given the recent posts about this guild, I'm not surprised in the least.
