Woah, woah woah!
I, for one can see the motive for that dislike. Sorry man!
1. Lack of action - The dark effect of many of the clips, coupled with in all fairness not that epic of a battle leads my finger to that dislike button... I mean seriously though, why would I watch you, fighting at a mediocre level, with not alot of action at all. Featuring: Repetitive clips of effectively the same thing, unfitting music, with the video utterly unsynced with it, and failing comepletely to be decent at PvP
2. Watermark - Self explanatory. Please just buy it, ok?
3. HD Compression. Your problem here, is that you have compiled to 1080p, BUT your video is not true 1080p, therefore there is no point. This leads me to my next point...
4. Record in HD! - Sorry man, but welcome to the internet. HD is a must for growth these days.
5. "Sorry I was crap back then" - If you openly admit it was crap, then why upload it?
6. DON'T EVER, EVER PLAGUARISE. JUST STOP. DON'T CLICK DOWNLOAD ON THAT GOOGLE IMAGE. LAZY SOD. Sorry, had to get that one off my chest. No wonder for the dislike, since that thumbnail is alluring of a high-quality video.
In summary, I'm sorry man if I came across as rude, but it irritates me significantly that you came complaining over here because of one measly dislike, confused as to why people don't like your 'comment' (content?)
The same is evident across all your other videos:
Plaguarised thumbnail, coupled with tacky editing and unfitting music
