I'm missing the option "Depends on my opponent".
Because... that's what really makes invasions fun or incredibly frustrating for me. The character Veles fights and their writer.
I've had some really great duels, off the top of my head I can name the fights against Kian Karr and Phylis Alince - one ended in a loss for me and the other was a draw. What connected these fights was probably the same willingness to lose as to win. Of course we wanted to win. We had the same chance of winning. The characters were fairly nicely matched, but on the other hand, we were pretty fine with losing as well.
That is not the usual mindset, unfortunately. I've always been told that "invasions are about winning at any cost". Well, that is just great mentality to have!
....
No, not really.
There is nothing more annoying than trying to find a good opponent and bump into a powergaming munchkin. A 3 metre tall donkey of a race you've never heard about, but wookia says they're really powerful. It is quite possible they are mutants/cyborgs/hybrids (or all!), which makes them even more awesome. Of course, this character is clad in all-resistant armour and is Force-dead, yet can use the Force in Starkiller fashion.
The character has a cloak of invisibility, glasses revealing one's position, weaknesses, alignment and power level, a necklace that grants them 120% protection against any and all sorts of powers that could actually hurt a Force-dead being, an indestructible lightsaber with crystal +20 attack -5 defence and a helmet of +20 defence -5 attack. Naturally, the character knows every power that is convenient at the moment.
Oh, you sonofa....
The player knows what kind of character they have. They know they are going to win. The character is tailored to roflstomp anything that gets in their way. And if you actually find a way to deal damage, you are accused of godmoding/metagaming and playing unfair.
It all goes to hell then.
So as I said, it's all about the opponent for me. If I meet a player hellbent on winning, I can say I am not going to enjoy the fight very much.
