Hey Everyone, after many catas with new/older players alike, I've noticed that players are having difficulty succeeding with casters in this new Update. Since Nick (Stok3d) put out a casting guide earlier, there still needs to be more clarification because everyone still does not understand the true casting concept. Therefore, I have created some screen-shots and had one of my guildies clean them up that way everyone can learn a few new things, take some tips, and become Pro Cata-Star Caster's (Thanks Ryan - Gopher10 for the PRO Image and work, you just helped to make this thread even more OFFICIAL).
A few notes, this thread is intended to help others out, so be sure to play CLOSE ATTENTION to everything listed (stats, gear damage, group placement etc). If you already use these "Best Practices", then you are already a Pro Caster and just need to keep doing what your doing.
Remember that your every move needs to be Spotaneous, not pre-planned. Pre-planning only makes you seem arrogant and foolish and most people will be too intimidated to join your runs. Also, do not take offense if you end up getting kicked from games. Some players simply cannot handle having such a Badass character in their game (like the ones in the pics below) so they tend not to do runs with people like this. Its just an inferiority complex, eventually they will come around.
Another thing to keep in mind, is that you need to click on every high level wellable that comes your way. This is to ensure that you use your pro build to well something godly, that way you can put them on the MP for a reasonable amount (usually 2-5x the normal price) that way you help out the rest of the community and recycle FG back into the system. When your welling with your team, drop high level items into the well (like if your lvl 10-15 drop in 55's) that way your team has a well experience like no other and a challenge to post/brag about.
Ok, what you've been waiting for: These pics are simple and to the point. They should quickly tell you all you need to know, w/o a huge wall of text to filter through. Following these steps will set you on the path to becoming the next McClain, (well, hes got GG gear the rest of us can't touch as well as MQ attempts/GP's, but everyone should have hopes/dreams/goals).

Oh yes, if you have anything to add to this to help the rest of the community, please post it here that way everyone can learn to grow and become better at this new Casting system. Gl to everyone lets see some awesome cata's!
