at the start of WOTLK 19s were able to do WG by just getting there and were buying the PVP BOA gear which was haste loaded and a few had some resilience, in fed/mar 2009 blizz did a buff that doubled the effects of resilience for players below level 70, but did not seem to affect 19s due to so few pieces. when argent tourney came out it added PVE heirloom vendor, ironicly were better in PVP due to having crit
shoulders were enchantible by mains and mailed to alts, was nerfed on the great twink nerf of WOTLK
into van WOTLK which should be already in classic WOTLK, blizzard buffed caster weapons rather huge, to the point a 19 BOA staff was better that the epic staff of jordan used in the 39 bracket. i think on old twink info someone did a stat comparison of the BOA mace at 19 vs wowhead database it wasn't till i think level 54ish a mace stat wise = BOA, at 29 the near equal stat mace was into the 60s. caster BOAs became BIS even though some caster weapons in 29 and all in 39/49 that were +35 enchant capable
