Hey friend... I know I should have your side on this since I've known you for so long. But I honestly can't help but agree. It can be kinda hard in the beginning to put a few paragraphs in dialogue, but theres several techniques you can look at and try to focus.
I'm gonna place an example of an RP I'm doing now, and I feel really arrogant for placing it here, but I just wanna pose a few pointers cuz Iwaku has taught me a
ton during my time on it., and my partner
faaaar surpasses me, but I don't want to put one of her replies without permission. This is a small fragment of the conversation we're having in our story.
Torin just shook is head at the man, letting loose a heavy sigh as he stared at the reaching striders below them. After a few moments, he slammed the trapdoor shut over the opening and turned to the older male. "I know that you want to get to the camp. But I already told you all the information you needed to know.". He pointed down at the infected swarming the street below. "They're coming from the camp, go against their current and you'd get there." Torin turned his finger to his own chest and then to Robin. "I do not matter more than she does, and coming after me was a stupid error. I would have been fine, thats not the first time I've gotten into that sort of situation. And even if I wouldn't have been fine, my point still stands. You need to worry about your sister and nothing else." All this was said with out a single raise in they younger's voice, as if he had never faced the edge of death, as if he were having a casual conversation with a stranger. He shook his head and plopped on the roof beginning to sound stressed, small wavers and breaks appearing in his voice. "And even so, I still think going to the camp is a bad idea, since you'll be plunging head-first into a swarm of danger and dragging your sister with you." Small tears welled up in his eyes for seemingly no reason, not even he was sure why he suddenly wanted to break down. Despite his happy nature, Torin's mind was suddenly filled with self-doubt and the urge to give up and give in to the end of the world. But he just furiously shook his head, pulled back the tears, and looked off into the distance. Loosing himself to a few memories that rose up in his mind.
He had always been really hopeful and happy, never letting anything get his mood down, even on the days were he just wanted to let go and end everything, he put a smile on and went on like nothing was wrong. He never vented to anybody, never got in anyone's way or released his problems in fear of being a burden to someone. He understood that letting out his true feelings was something that was healthy and natural in fear of bottling it up and exploding, but he hated the idea of putting his problems on someone else's shoulders and dragging them through his mud. Even when all this began, he forced through it, kept a smile, kept his hope. Though, if it really was the end of the world, he wasn't sure how long he could keep it up. He didn't know when he would finally reach his breaking point and while he liked to think he could go on forever, the truth was...
He really couldn't do this alone.
In midst of putting the basic dialogue, you can put what goes through the character's head. The things that they may wanna say but don't. Who are they looking at? What are they doing while they talk? Are they anxious or tired? How do they feel and how do they come off as? Does their conversation bring up memories?
Now as said, this can get repetitive, but thats why you don't put all those details in one post. You spread them out throughout the conversation, and if you run out of details, then thats probably a good signifier that you you should move on the plot and get away from the dialogue since a roleplay with only dialogue tends to fall flat.
When you're not in dialogue, put actions, thoughts, feeling, memories, urges, gestures and everything about them into that detail, but once again, spread it out. This way you don't run out of details before your character advances forward. While it may be hard to pump out three paragraphs, you can only stick to one nicely detailed paragraph and get away with it fine.
I'm sorry if this drug on, and if you feel I may be against you (I know how you are under pressure and on the fighting side). But I just wanted to add to this and give some tips...
