I like Thor leeches better for a couple of reasons:
1. With a SG, the xp on Day of the Stars becomes absolutely sick. I leeched a trans from 98 to 99 in 1 hour.
2. If the leecher dies, it's a simple task to get back to the dungeon and you don't waste the leech's time.
3. If the leech dies, they can come back super quick and don't have to pay the 10k entrance fee that LH3 requires.
4. No MVP's in Thor that destroy you before you can hit a hotkey.
5. I find the LH3 monsters (because they're semi transparent) are sometimes hard to see. I often die because I'm attacking one thing and don't realize that there are several, but that's just because I'm not very good sometimes.
