Does Lee Sin (Centered)'s ability 'Other buffed friendly units at my battlefield have +2' include himself, and does 'my battlefield' apply when he's an attacker?

Ruling: Lee Sin does not buff himself due to the word 'other'. His 'my battlefield' refers to any friendly buffed unit at his battlefield location, which includes when he is an attacker.

Nuances:

• The word 'other' explicitly excludes Lee Sin from his own buff effect
• 'My battlefield' applies regardless of whether Lee Sin is attacking or defending
