To respond to the people who responded to me: I wasn't just talking about me seeing if people can dodge or not when I said I don't need to use a parser. I am watching what others are casting/using, too. Just seeing the total numbers doesn't help me know what the problem is... just that there is a problem. But, watching them helps me realize what they are doing wrong, if they are using the wrong rotation, etc. It's pretty easy to watch... and not hard to watch in titan extreme because every single move is 'predictable'. Also, when people do parse... I am told I am usually one of the top if not the top, so I know I'm not doing anything wrong... but then again, I knew that before people started going crazy with parsers. I don't care if I'm number one or number two... just that I'm getting the job done and being the best player I can be. It's just common sense. If you want to use parsers on a dummy to help someone learn or practice their rotation... that's another story.
Sometimes you get lucky with crits or not, and there's your variable for good players... but you'll be able to tell if someone is using the wrong rotation simply from watching them. Unfortunately, I don't know melee dps well (I haven't leveled one) so I cannot be as critical with those roles. I do, however, watch all casters and bards to see what they are doing... and it is pretty easy to see if what they are doing is right or wrong.
Anyway, another reason I am against parsers: there are so many fights where they simply won't be a good reflection of how well a player is playing... most particularly with fights involving a lot of adds or dodging. Turn 4, Twintania, Titan Extreme, Garuda Extreme... all these fights are hard to 'parse' because so much is going on at once, and different jobs are optimal for different sections of the fight. There are certain little tricks in all of these fights that will make you more effective... and that just isn't raw damage. That's experience and knowledge.
One example I'll give is how I treat conflags and jails in Titan ex: I get my dots ready, bane them onto the add, and fester. The damage is effective and helpful, but would my damage be better if I just used my festers on cooldown rather than timing them for those moments? Probably... but to me it doesn't matter because parsers can't show who is playing smarter... just who is doing the most raw, parsed damage. This is why I watch other people... Let's say there is another summoner in the fight, and he is out-dpsing me... but only because he is using fester on cooldown rather than using it at optimal moments. He never banes or festers the jails (this actually happened in a titan group I was in, and I noticed it because I was watching him). Then we start to have issues with adds because he isn't saving his cooldowns for the right moment. That's why I'm saying using parsers as the end-all be-all of how good a player is... is a BAD idea. Instead, I watch what is going on and give advice.
How is this fight hectic? I have it down to a science because the fight is a science, and yes I maintain my rotation because it's easy. Everything is so well-timed and Titan always follows the same rotation. I don't watch five people at once... I watch one or two (doing their rotations if I feel they are bringing the group down), but I will notice if any player dodges in the wrong direction or goes to the wrong place. Perhaps it's an old habit from playing WHM only in 1.0 -- I am always watching the party bar in addition to what I am doing, and dodging with my peripherals. I've been doing this fight for weeks helping people learn the fight... I call out abilities before they happen for new players, so yes I can maintain my proper dps and still watch others. I'm surprised people are challenging me on this because I assumed anyone would be able to do this if they have the fight memorized.
