This again? We have went over this so many times lol. But please, people continue to feel free to think your way is the only way. CoS can be done with many different types of weapons too. It's not a requirement to use recluse and swarm. My team has loaded question, outbreak, random GL or rockets...you just have to have those things to do a specific strat to one phase the boss. If you can do the mechanics, you can beat the boss with any number of weapons.
"After a long day in the office, I just want to do pve stuff."
Ok, so do pve stuff, nobody is forcing you to do exotic quests or any pvp at all, that's your choice.
I know that you can do CoS without Swarm but my experience is being kicked out of lfg-groups because i dont have Swarm.
I really would like to to, but getting a quest (you payed for) only to find out at Step 4 of it that you have to to pvp to finish it is just not fair so sometimes its only your choice to delete the quest after a good amout of time invested. Thats why i asked for alternatives for pve players. Bungie kinda showed that this is possible with parts of the dorn-quest.
