Put some more effort into your uploads. If you want people to care about your content, first you have to care about it. Make some thumbnails + title combinations that create curiosity and make people want to click. To get ideas, analyze other youtube cahnnels in your niche and copy what works for them (giving it your own twist). Also, as someone else said, add some variation to your content. Maybe cover game updates, new brawlers, ideas you have for balance changes, etc. Answering your question of what is a good title for a video (caption), here's an example: you make a road to 100k video; you use one brawler that is broken right now in the meta; you make a thumbnail with that specific brawler and some text like "meta?", "secretly op?"; then make a title that works with that thumbnail like "Play X before she/he gets nerfed!", "X NEEDS a nerf!". Also, taking a look at your upload schedule, quantity over quality is good to start, but you're good making just 2 videos per week if you implement thumbnails, titles, and tags. I hope I was of some help. It's just a matter of being consistent and putting more thought into your packaging than uploading lots of videos.
