I got caught by this, although not as badly as some because my affected gun (LAW-303 Jungle) was only at about 35% TT when I bought it; I presume it was a mob drop, because it had a zero tier level. I have level 40 (soon 41) laser sniper, and the weapon was well and truly maxed. Now, I'm below SIB range and it's essentially unusable by me. I also don't know whether it will sell on auction at all and if it does I will probably lose peds on it; I assume its maxed level will be around level 50 laser sniper, and there aren't all that many people in that range on Arkadia; certainly not now with MM coming up. So there is a 150+ PED gun sitting in my storage waiting for me to gain 8-9 levels. Peds down the drain, and I don't have all that many in the first place. Arkadia devs say there will be gaps in the SIB progression. Certainly right; in this particular case the nearest fit (below) is the standard LAW-303 with a required level of 27 so maxed at around level 32 - I assume, anyway. Next up is the LAW-303 Desert with a required level of 42 - a FIFTEEN LEVEL gap. Personally, I think that the Arkadia devs need to make filling in the gaps in weapon progression a #1 priority, else lose most of their residents. I looked on Ark auction yesterday; there are literally no guns at all on auction suitable for my level. Two Calypso guns, one way below and one way above my level and both at really high MU.
