Points 1, 2 and 4 are all just plain stupid - the rest however, fair play.
Point 1 - The weapon is/was perfectly fine. Its increased damage is understandable as its suppose to be viewed as a better version of the 15s. You need to remember also, that the scope of the WESTAR isn't used by most of ARC since its literally dogshit. Therefore, the placement of increased firepower just seems understandable. Furthermore, this just makes your point irrelevant as it comes across as you having a mad sook about not getting an extra 10 damage on an NPC, congrats!
Point 2 - A grappling hook can be easily abused by any player on the server, the main reason it was never implemented into some kits was solely due peoples inability to actually use it properly. Overtime, ARC has showed their ability to use the equipment in both the right and wrong ways, however they're obviously going to be more trusted with the equipment after being placed into a 1-month traineeship opposed to someone who just donated for Clone-Force 99. Similar to the first point, if you care so much about having one then why not aim at joining ARC.
Point 4 - The reason RC will never be looked at as a more profound and 'elitist' regiment is because its donated for and most people who do donate for the squads are considered to be 'trolls' or just plain shit at the game. I'm not saying EVERY squad is this, but majority of the time they are.
Although, this point may have been relevant back in 2016 Gateway where the whole concept of RC would have possibly been changed, but guess what? Its not 2016 so goodluck with that.
Anyway, my last point on this is just place the current RC Squads next to ARC and view their skills against one-another. I have $150 on ARC being at a WAY higher standard then what RC is, the reasoning behind this is because ARC actually benchmark and ensure their skills are ALWAYS at a higher-standard whereas you hardly see RC train or even do anything to keep their skills relevant after becoming a member of one of their squads.
Overall, I think someone honestly needs to call the waambulance because it seems like the people who have issues with ARC currently are just the ones who have never been able to actually make it near joining them.
I don't want be considered toxic from this post, however I do believe ARC should be somewhat recognised as to why they have unique kits and how hard they actually work for said kits, me for one would be pissed if I did a traineeship for 1-month of my life just to get some cool weapons and have them removed the next day because someone started sookin about ARC killing NPCs faster than another player.
