How am i suppose to get new weapons or upgrade gear faster if i can not join a run i find it kind of stupid IMO so i really looking to maybe change servers soon
Very easy simple solution, you already have THE job, which is Corsair, here are your steps:
1. Farm Sparks, get your Trust NPC, grab some level 117 Spark gears, weapons, bullets, corsair ring, accessories. Extremely accessible.
2. Start doing Courier Coalition task to rank up max daily, should take 2 weeks till you can do Marjami Delivery. Grab a few other level 117 Bayld gears, choose range accuracy, range attack, etc.
3. With a mix of those level 117 Sparks + Bayld gears, start shouting or joining SKCNM 20 shouts, grab your Chapters 1-5, start upgrading your Relic + Artifact = choose the ones you think its best. Also do Skirmish party, you should be more than qualified.
4. Start joining shouts for AA, you should be totally fine for this with your 109-117 mix gears especially if you have all your weapon skills unlocked. This will let you get 119 on some of your pieces, you can also redeem your Sparks for Chapters 6-10 if necessary.
5. Now you can join Delve 1 and farm plasm and get those few 119 stuffs you can use. And join Delve 2 afterwards and grab a few other 119 gears and augment them accordingly.
It should take roughly a month or so playing casually to gear your Corsair. Even less if that is the only thing you do. You can probably join Delve 1 with a mix of 109-117 gears immediately. Delve 2 is ok if all you do is full on support with occasional damage, but may be under geared at 109-117. Most Delve 1 party is consisting of 2DDs, Whm, Brd, Sch and Cor.
