Attr-compounds instead of Res-compounds, but also lvl 140 vs lvl 180 and less MD/DP.
As far as the price, I feel like keeping it at 50k instead of lowering it will help to prevent the market from getting flooded with them, which will help in keeping the resale value high for those that do shell out 50k for one (or already had one). It's a really nice shield though, so I'm happy to have spent 50k on it.
This is actually the reason we decided to sell it for 50k. xoxo
