Petra, here are a few other things that might be worth adding to that page:
Crafted spellbooks (even those with no mods) are never blessed.
You can't use an Advanced Character Token.
You can explain it better, but maybe add something about which items sell in quantities of 500 on other shards but start out at 20 on Siege and the quantity doubles after that. I'm thinking specifically of the small gems but suspect there may be some other items that also differ this way.
There is no facet on the shard where you can gather resources at double the rate that applies in any other facet.
Having Arms Lore skill gives you slightly better resists on armor and slightly higher damage increase on weapons than on other shards.
During a taming attempt, the character doing the taming cannot become invisible by any means.
In all facets of the shard, using Reveal spell and Detect Hidden skill will reveal characters that are not in your character's same guild or alliance. (On other shards, Reveal spell and Detect Hidden only reveal characters outside your guild or alliance when you are in Felucca. On other shards, I think they still only work outside Felucca to reveal characters in your same guild or alliance.)
On all facets of the shard, your character may have stamina loss when trying to walk through other characters, animals/monsters.
