I had a quick look at the code for these spells and there's quite a lot of issues. I'll try to state them as clearly as I can:
In the case of the first ability (Water Bomb 1st Technique )
- You use TSAs or Waits these are inconsistent and should not be used
- The Ability is not MUI or even MPI
- There is no configuration for the ability
- The main code is written inefficiently, instead of making each dragon separately you could use a loop reducing the lines of code to 5 for creating them instead of 32
- Same as above could be used for damaging all units and moving all of them
- don't use loop timers of 0.01, use 0.03 instead (or even 0.04)
- You only need one timed trigger (Loop trigger) to control all movement and damage of the dragons
- Use unit starts the effect of instead of unit begins casting
- Use Set Unit X/Y instead of move unit
- Do not use terrain deformation effects, they leak
- you leak many, many locations and unit groups
In the case of the second ability (Water Dragon Ride)
- The ability suffers from everything the first one does and some other things
- Specifically only works for player 1 (red)
- Don't lock player cameras to units, this should not be done except in the case of Camera systems and other similar submissions
In the case of the third ability (Ice Water Technique)
- Everything the first one suffers from also applies here as well
- Leaks regions
Essentially all the basic stuff is lacking in these abilities, I strongly recommend having a look at our tutorial section for making abilities
http://www.hiveworkshop.com/forums/trigger-gui-editor-tutorials-279/
and review memory leaks here:
http://www.hiveworkshop.com/forums/triggers-scripts-269/things-leak-35124/ (which is what I'm referring to when I say things leak)
sadly these abilities would have to be almost entirely re-written for them to be able to be approved by moderators as it does not meet the
Rules of this section
Any terminology I've used which you're unfamiliar with will probably be explained in those rules (&/or common tutorials in the GUI tutorials section that I've linked)
I wish you luck with your future works
