I am fully aware on how to "use his amazing techniques." And I am fully aware that anyone with a reaction time can successfully avoid any serious damage from these techniques.
Ask anyone from ~kai~, I go out of my way because eyelaser kills amuse me so much. It doesn't change the fact that the damage they deal for the ki they cost is minimal, and requires targets who don't like moving and enjoy being smacked around. Freiza's laser is INFINATLY better because the ki cost and damage is done in an instant- beyond that, you can be charging. For every MILLISECOND one is fireing eyelasers, they arn't recharging ki. It's high cost to actually finish off an entire laser is quite an offset, as your opponent will more than likely be ready to attack by this point and you're going to be down that much ki.
Scattershot is borked, is broken, is busted. Regardless of distance, you can guarantee many of ones shots to just detonate wherever they are regardless of when you right click. The only time it is "deadly" is when one gets smashed into the ground with a slow recovering charecter who also forgets to hold spacebar, so the piccolo can fire them without the need to right click. Otherwise, they're both laughable and saddening because they actually have potential.
Speed is the most important aspect in most situations; most of the "slow" charecters have an ability or two to offset this. Freiza has the laser, Gohan and Trunks have fast trans, Krillin is a BEAST when he transes, and Piccolo has to wait for one million PL in order to get a crappy multiplier and a crappy trans.
Please don't delude yourself into thinking he's a good charecter. Dieing to him is in many ways more humiliating than dieing to an untransed Gohan or Krillin; Krillin's got spam moves you have to worry about constantly, Gohan's got quick techniques at low ki cost such as the shield and in some circumstances the power beam. Trunks has multi-hit, and Freiza is just plain deadly. What does Piccolo have? He's a mess and a hybrid of all the other charecters; he does the same things as basically most of them, but poorly.
Please, don't go around insulting people when they realize a charecter is flawed; provide reasons other than "I AM VERY GOOD" to back your statements. Otherwise, it comes off as both degrading and insulting.
Don't get me wrong; Piccolo is a great concept. Very origional and great potential. He's just got a few design flaws (Masenko is garbage compared to the power beam, eye lasers are too weak for their high ki cost, and scatter needs to not randomly explode regardless of distance when right clicked, trans is iffy) which make him... less than satisfactory when compared to the others.
