So an accurate prediction is hard to make for pretty much anything. But I'm curious, especially from the Eldar PuGs experience so far, what you think the first version of the campaign will look like when enemies will very likely be able to choose who they can attack and on what map.

Who do you think they will attack, where, and why?

All attack lsm, but they dont care, cos outnumbered.

That's an interesting point.
I suppose only time will tell, but its amazing how many times I hear in game and on the forums that people STILL skip elder when they pop up on the queue.
I personally don't skip any map or opponent. Some maps suck a bit, but I feel the races are fairly balanced at the moment. No one is a guaranteed win or loss. Its just the weapons within each faction that kind of need balancing.

You think the players will be able to choose who they're attacking? I think the campaign system will be a spoon fed prompt "x match/map is critical for y reason, winning on it gives z reward." And then we grind the daily maximum.

Considering how many there are who hates fighting against Eldar, then I guess we will have a semi-tough time as only the guilds will really attack us or maybe we will merely be ignored.
There are also the future where all the other factions simply deside they hate Eldar and then "eradicates" them from the map.

Regarding actual "Foresight" which the Eldar are known for, regardless of whether their actions in the lore support this (damn you Eldrad). Then it would be cool if this somehow played on the map, so we would be able to see where the enemy was going to attack ingame and what their "goals" are. I know it would be quite useless, as you could simply just swap to the other factions to see it, but it would be a nice touch.

Even something where the other factions get a general reward type: "You will earn RTC if you win this match." and the Eldar's one said: "You will win 100 RTC if you win this match."

As to the OP's question, I foresee that no-one will care at all and will just choose the matches that provide the greatest rewards.
Or, more accurately, some people will care, but because of current player numbers, it won't be possible to pick and choose to best benefit the faction and everyone will be stuck doing the matches that benefit the individual over the collective.
