people with little/no cash to buy these items will never be able to compete with oters.
guildwars will be won by the guild whos members spent more to get their items high upgraded/has more members using those +50% attack/defence thingies
instead of hearing shouts like "XY guild rescuting lv55+ people" we will hear "xx guild rescuting people with over xx cashshop-points to use"
im not funny, i know. but these items seem to make one a way too much stronger then others, who doesnt use them
