Hi. A few questions...
1. What are the main fleet comps?
2. Is there a roam every night or planned or just the random and... "Hey there is 5+ people on and a FC... lets do a roam?"
3. (Understanding that PVP is not an isk making option.) How does your scouts/ecm earn any loot if they are at optimal or next system?
4. Do you require only mains or do you allow trialist to use alt/sub-main. (Sometimes WH life can be a bit boring. More like alot of times.)
Roigon (Hi you lurker!) answered your questions pretty much spot on, I'll just add a bit to them.
1. While we do have a few "standard" fleet comps, you can always fly skirmish, jams, logi, scout, or some other role if you don't have the skills and/or ships to fly the main fleet comp. Most of our internal gangs are very flexible, "Short range shield cruisers" or "Assault frig of your choice," "Let's go out in long range armor whatever..." regardless of the gang, there is ALWAYS a need for skirmishers (specialized scout/tackle role flying interceptor). ECM support is usually welcome on most gangs, and logistics can be useful quite often, also. A common sort-of mistake I see new members make a lot is trying to flying everything all the time, this tends to lead to a lot of unnecessary losses since they are still getting the hang of flying in nullsec, flying with us, getting to know us, etc. I usually recommend that new members pick two or three favorite hulls, one or two favorite fleet roles, and just stick with that for the first 2-4 weeks, till you get the hang of us. In other words, concentrate on the role (or roles) you want to fly or want to learn to fly, more than the fleet comp. When you specialize in a few roles, there is a place for you in nearly any fleet comp.
On #3, Roigon answered it nearly perfectly - and yes, Roigon, we still give loot to those who lost ships after battles The best advice I can give is to balance isk making and cost-effective flying. I spend almost zero time on isk making - when I log into the game, I want to spend my time making explosions, not staring at an asteroid, hauling PI, analyzing the market, etc. So I tend to set aside some time every now and then (usually a week every month or so) where I will concentrate on fattening the wallet hardcore, then just float off that isk till the wallet is low again. I also try to take advantage of the occasional opportunity to really bankroll my wallet when those occur - like for example, when they announced the battleship changes, I made a bunch of Dominix's before the change (at a cost of about 62-65 million each), sold some of them as the market spiked up to 100-110 million (clearing 1.2 billion), and am sitting on the rest, which I will sell as I need funds over the next, oh, probably a year. As I also fly VERY cheap (my average ship loss is 12 million isk), the isk I already made means I won't have to think too much about isk making for a long time.
One thing I do recommend to people considering applying is to make sure you have enough isk to fund your pvp for at least 2 or 3 months before you join Agony, that way you can concentrate on making explosions and getting to know us. Struggling with isk at the same time you are getting used to nullsec makes for a less enjoyable experience.
On #4: This is a question best explained by your recruiter, but yes, Agony is a corp of mains. We want your focus to be on Agony. To be more specific, it's not about the character, it's about the person behind the character - we want YOU flying with us fulltime, on whatever character you want, the character isn't who is joining Agony, the person behind the character is joining us. Leaving alts in industrial/NPC corps is perfectly fine, but leaving alts in another PVP corporation (especially one we may shoot at!) is not acceptable. Spending most of your time on a character flying with others, and only logging onto your Agony character when there is something "interesting" going on, is also not acceptable. Hope that makes sense.
Oh and one final note: Echo squad best squad!!
