Is this Pingzapper service guaranteed to eliminate issues like this?
If so I might consider paying 30 bucks for a yearly subscription, however it would make FF14 cost even more on top of the already fairly high fee given I also rent out an extra retainer.

I'm normally first to call for patience and understanding when MMO companies have issues like this, but those MMOs usually provide free services such as TERA where you can fully experience the game for free and if you do choose to buy more inventory bank space it's a permanent one time purchase.
I understand why a game of FF14's score is pay to play and it's hands down my favorite MMORPG of all time alongside TERA, FF14 now is slightly better too, however for a game we pay as much as we do for....issues like this are inexcusable.
