Your rewards in almost anything are proportional to the effort you expend. Alts are work to maintain.
Saying (or even implying) that alts are exploits is the same as saying (or implying) that the player who spends Fuel to speed up return times so he or she can raid thirty times in one day is an exploiter. If someone wishes to create an alternate account where's the exploit in that?
"They get more unis than me with their 10s of alts." And? lots of people get more unis than me too, and I have alts - doesn't make them cheaters/exploiters.
"They load them down with unis so they can smash noobs." I'm a lvl 50 noob, and if I took my WF off for a few days I'd show you some raid reports that make me look like I just built my two-way - and that doesn't mean those who open me like a bag of chips are cheaters/exploiters.
"They farm WPs with their alts." They still have to PLAY the game, so what if it's not their 'main?'
Alts are presented by some as a bogeyman that is the cause of all problems, and now, with the new individual rewards system not even implemented yet, they're being blamed for problems that don't exist.
As far as I can see, the most complaining about alts is done by those who are jealous, either because of the 'rewards' the alts garner their main accounts, or because of the time some people have to invest in their alts, as opposed to those who don't.
You can be level 50 and still get wiped in a raid, or you can have been playing this game for years and still feel 'poor' compared to someone who drops hundreds of dollars on Fuel and keys. There will always be someone with more luck, or skill than us, that's life - and games too.
So take some time from complaining about problems that don't exist yet on the Forums, and go take a flag, or loot until you find a nice unique, and please stop blaming alts for everything that goes wrong.
@Nephy - a good idea about the different IPs required for an Alliance, although mine might have a problem as we are all on the same one :/
