The i70 grand company stuff we can buy with allied seals stuff, by the time we can afford one piece of that, we can get multiple pieces of the i100 weathered gear, which is clearly better than the i70 stuff

So why should the i70 stuff cost an arm, a leg and a baby, when we can get the i100 stuff for just a baby?

The i70 helmet/gloves/boots cost 600 allied seals each
The i70 body armor/pants cost 1000 allied seals each
The i70 weapons cost 1740 each


The i100 helmet/gloves/boots cost 400 allied seals each
The i100 body armor/pants cost 660 allied seals each
The i100 belts/accessories cost 100 allied seals each


And for most (if not all) people, the i70 stuff is only good for glamour, which is pretty expensive/time consuming since it takes ages just to buy a helmet, let alone the 3800 allied seals for one set of gear, even more so with the fact that it's locked with your free company, so if you change company, you can't use anything you had from your last one.
