I'm happy to help test stuff, but I'm back at work now, and don't get to play for very long.
I really should do something about this signature.
Defiant or Union?
I have many heroes including two 50s on Union. As i am starting to play on Defiant more i have 1 lowbie (possibly level 6) and one mid level (26 scrapper) heroes and one lowbie villian (thanks to MA arcs he is level 7 atm, corruptor).
So i can swing both servers and both sides in case of Union, if required as MA auto SK you to the minimum level needed for Arcs.
PS: I am repeating again myself, my idea is intended for testing custom mobs, not all arcs as standart mobs won't cause much trouble.
If you ever want to do some testing on Defiant, Do try and grab me. Have plenty of Heroes and Villains on Defiant, but sadly nothing on Onion 
I waited until a Mothership raid was over, and then started asking on broadcast.

Thanks Xemulas. I will hold on to your word in future as soon as i finalize my custom mob. The more i play the more weird things i see about custom mobs.
To be honest those custom critters what's making MA arcs fun for me but the more i play the more i understand they need a better test than any other aspect of arcs.
Let me give you some examples:
1- On one mission arc i did pretty good as solo and with a friend as duo. When we wanted to try it as a team on higher difficulty unluckily all the mobs in map was EBs. We lowered difficulty but that also didn't change anything.
2- A similiar thing, i completed one lowbie arc without problems and loved it. We started a MA only team (actually a trio of Tank, Defender and Blaster). We could handle the mobs as a duo but when we became a trio the mission become an annoyance. Custom critters become way too overpowered. We tried many times but no chance and left that one as well.
People putting a lot of effort into that missions and creating that fun critters. It is a real shame sometimes things got out of hand and people forced to leave this beautiful arcs behind and move on.
So if there is anything i can do to help those people, i will be happy to do it.
If you see me online when you want to test then just give me a shout, either @kryzel or @gemheal are my globals. I will gladly help you out.
I do know what you mean as I have had the same issues testing with my blaster then when i added a defender to the team it became very difficult to do even on the easy setting.
Oh yes I forgot, I am on Defiant
I'd be happy to help with that, (I think you're even on my global) got chars on both servers, and different types of ATs.
Defiant 50: Blonde Justice inv/ss; Lady Aminta emp/elec; Sierra Colt merc/traps; Tess LaCoyle elec/elec (blaster); Powerstorm elec/elec (brute);
Union 50: @Steel Dancer WP/DB; Blast Pulse Fire/Rad (corr); Bitter Twilight Earth/Psi (dom); Compassionate Emp/Psi;
Freedom 50: Incandescent Blaze ElecAm/Fire;
I play on both Defiant and Union. Send a gobal to @Frosty Robot, and if I'm free I dig out an apropate character on the right server and help you test stuff.
I really should do something about this signature.
Thanks Steel.
Problem is not actually me, on worst case scenario i will wait for one Saturday and test my arc with Circus members or do little tests with my friends.
Some people can have hard time to find 8 people or even 4 people to willing test their arcs while they get nothing in return. Heck, sometimes they even don't accept to fill your team for a minute for spawning bosses... even if you say you will run a test for your MA mission etc. etc.
I am a lucky chap as i have some really good people as friends in this game.
If everyone can post their global i will make a list so people can ask us when they want to run a test.
I am seeing this a temporary tho'. MA is still too young and most of us are inexperienced about creating custom critters. We will learn how to design them for their targeted level range.
Anyone having trouble finding people to test their missions on test? Especially ones designed for certain level range and with custom mobs?
If some people having trouble finding people, especially teams to test their unpublished arcs i am thinking about starting a testing team for a certain evening of a week.
Why am i asking this?
1- I had some problems in the past
2- Some custom mobs, especially low level ones while act brilliant on solo/duo they easily become disasterous on more populated teams.
So, any one need this kind of thing? Who wants to take place in that testing team?
