Forget guild leveling look at the store bought reward mechanisms for guilds. So, I can buy +2 to all stats from the DDO store for my guild. Let's say I can reasonably afford to do this for 1 hour per week. If I am in a guild of 7 people with similar ability to afford stuff from the DDO store, I could have +2 to all stats for 1 hour per day. If I am in a guild with 168 other people, I could have the buff constantly. R.I.P. small guilds.
I thought the DDO store was going to be limited with regard to the magnitude of impact on in-game character power, but more and more, the power creep from DDO store bought advantages makes me sad. I fear that we will indeed soon have a game tuned to the point where not spending money in the in-game store = being horribly underpowered and progressing at a snail's pace. I would like to add my voice to those saying that the latest update is a step in the wrong direction for the game. (Never mind the other nerfs...)
