The challenge in this champion is his ultimate.
 * From what I see, I believe you should see if the entire kit works with itself. The issue with this kit lies in the lack of synergy with the abilities, most in due part because of the choose-and-select basic abilities. It sounds nice to be able to make your own summoner-spell sandwich and not be limited to only two... but I believe the basic abilities need to veer away from summoner spells. As I pointed out for Randall, it brings too much complexity with little depth to the kit.

Berserk spell is widely used in any type of game why it is not possible in League?
 * So... umm, because fire in any type of game is DoT, why not have all fire do the same in League? I could start listing more than this one example, but you are making a moot point. Of course, we can allow a champion to cause an enemy/ally to enrage them, but just be aware, this is LoL and you have to try to mold it to LoL's model of abilities. Have you seen a champion have an ability that purposefully (with full intent) debuffed an ally or buffed an enemy? No, right?

Remember Bard's ult slightly gives buff to enemy champion by putting them to stasis.
 * No buff is given to enemies. in general just causes a portion of the map to be placed in statis. Being placed into  may seem like a positive trait due to, but with Bard, the purpose of the statis is different: it is more "Let's preserve this moment" than "let's save my arse."

If you are really a gamer and know the spell you can outplay a champion.
 * If you don't mind the outright criticism, your English is starting to become poor (although I assume it is not your first language, so I will not say much more). But onto the point I wish to make, you are necessarily saying that any player should be able to outplay another, even if . But I despise how you say "if you are a gamer"; that's a statement that sadly snobbish high-rankers would use. A champion should be enjoyed at all skill levels, even if they are supposed to be difficult to play to their fullest.
 * What does "counter" mean to you? Because it seems that your definition of "counter" by the above statement is "knowing the spell," when in fact it is much deeper than that. I can rant on more, but I hope you understand this point you make has no ground and in some way can be seen as immature.

''Putting a berserk to enemy mages/support/low damage tanks are very effective tool to counter the enemy. You can also use this skill to empower your ADC, for a given duration. You can also put the target berserk to drive them to attack you while tower hugging. There are many ways to use this spell.''
 * Yes, this would be quite effective in making the enemy non-AD focused champions run amok in ways they shouldn't. But for ADCs... they won't appreciate shooting like a madman when they may not want to attack the closest enemy... Once again, you could use this on enemies when under your own tower, but you do not adequately answer to what Primus points out. "...you're guaranteeing that the opponent gets butchered by a turret or your team without any counter-play." You can make this Berserk a CC so that it can be relieved, but it is an all-purpose CC that can act as a for enemies and a nonsense buff for allies.

There is more to say, but I believe at the current moment, you are not seeing what is the flaws of the ult, and in general this kit. Please review what this champion is in the LoL-verse and how its game is built up, and respond when you have taken time to humble yourself with newfound knowledge.
