The fact that you cant attach mods to the old armours & weapons all the way back to season1 is ridiculous. Its makes the old armours & weapons useless. You should beable to re-tier your armours & weapons from season1 and onwards to keep upto date with the new ones, that fact you cant is upsetting to alot of people who put alot of time and effort in to getting there gear maxed out, it is extremely unfair. Bungie this needs to be addressed, fix it.
