i have the highest tiered EMine M armor in EU - all parts tier 2 (first parts at tier 3 gonna come soon)
when i bought it, it was tier 1 besides one part. It grows with me, its perfect for my level, it keeps me away from too big mob and when i hunt small with it, its still eco enough to justify wearing it.
I made the Araneatrox quest in it and tiered it all to tier 2 in the process. I use to use defence enhancers in it, and they are cheap and seem to have a very low break-chance. Meaning: In 15k spiders i burned ~5 defence enhancer per part and tier. I tried it unenhanced once for like 15 minutes and quickly added the defence enhancers again. Way less faping (no more in between faping), way easier to stand a chance at old+ spiders. With big enough faper i can kill a spider dominant in it, we just tried that a few days ago.
This armor grows with me, its perfect for my level and it will stay perfect for a long time. I am level 40 evader now and i guess i will grow out of this armor at level 55. But then again at level 55 i might also dismount the defence enhancers and put on durability enhancers making it more and more eco. For more defence i can still start to build a shadow or something in that ligue. But for now i feel 100% settled! I love it
