[sarcasm] Yes! Let's further deter PvP in SC, and exacerbate the SC grind even more by penalising people for crushing their enemies as quickly as possible! [/sarcasm]
If you are forced to your WC, and have no realistic means of either turning the tide or getting out, then you are being dominated; it is then your decision if you choose to continue queuing solo against the premades/players that are dominating you. To reduce rewards for premades/players who dominate their enemies as quickly as possible would end up in even fewer people queuing, even fewer people bothering to grind out subpar sets, and/or weapons.
Noone sets out with the intention of triggering the domination mechanic, but if you are in a SC where the opposition simply have no chance whatsoever of winning you, and have given up the ghost from the get-go, then why prolong it unnecessarily? This, by the way, does not justify reducing the rewards won by the victors: on the contrary, the losing side should want to go back to the drawing board, get organised, and minimise the chances of a domination SC from ever occuring in the first place. If you reduce the rewards won by the victors, purely because their opposition played poorly/weren't prepared enough, then what message does that send out in a PvP game?
You aren't 'playing the system' if you're put in a SC where the enemy simply has no chance of winning you whatsoever. To want to drag out such matches unnecessarily a la pre-domination patch is, pure and simply, masochism. To reduce rewards for SC where domination kicks in will just be yet another nail in the coffin, and will make the grind even more OTT than it arguably already is.
How about we stop knocking people for playing in tight groups that assist one another? How about we, the playerbase, get more organised so that we aren't getting dominated in the first place? I mean, domination usually only kicks in when one side capitalises on the disarray and chaos of the other, so perhaps people should stop playing so...unorganised?
