With the 2x breeding again, I got the same thought as before. Can gigas be a one week raise or receive a buff? The current state they are in isn't worth the two weeks because shotguns can easily enrage them. Also, rhinos (a 2 day raise) can easily enrage a giga (2 week raise). Doesn't feel rewarding as a giga rider when you know you can lose your 2 week tame too easily.
Losing it to another giga in a good fight is only way I would want to see losing my gigas.
