I'm playing many class in HoW : Hearthstone, but my favorite is the Warrior.
Warrior allow you to play with weapons, armor, charge and enrage mechanics : it's really cool and fun.
But, the Warrior isn't equal to over classes.
Here is the Warrior :
- When he play with weapons, he can use it to clean the board but he lose health points or armor stacks.
- When he's using an armor based deck, he can create a great amount of extra-life but he can't do damages.
- If you play a charge based deck, the Warrior allow you to clean the board and do some regular damages but your creatures will be insta-killed because of their weakness.
- You can try to have a lot of fun with an enrage deck and do a huge amount of damages at one time but you can't survive until it'll be the good time to hit your opponent.
Now, compared to other classes :
When a Warrior want to control the board, he'll be using 3 things : Weapons, Charge, Spells.
If you choose to clean the board with your Weapons, you'll take damages. If you Charge, you'll lose your creature and if you use your Spells... Well, you'll be using a combo to kill one or two creatures (basically Execute with Cleave or Whirlwind), or you'll use Brawl (which is a legendary card), Mortake Strike (But you'll need to be low life in many cases), or Shield Slam (and you'll need to have your armor stacked).
In fact, for many players and many situations, the only way you have to deal with big creatures are x2 Execute combo or losing many health/creatures.
Others class can do it waaaaaay much better! They have much better spell cards and these won't affect their HP and their board. Look at... The Mage of course, and he can do insane damages to your hero, he can use AoE. We can take the Priest : he'll destroy creatures with 3- Attack Amount, he'll do the same with 5+, he can do 2 damages to all YOUR creatures and heal his little army, he can take the control of your creatures [...]. Now, try with the Thief : he can insta kill many creatures and do many small damages, way much better than you, by the combo mechanics.
And these cards aren't legendary. They won't hurt the player who's using them.
Take the others classes and it's the same thing : Warrior lack of CC but he's not stronger with the unique tools that he can use.
In game, it simply result in a weakness for the Warrior.
The thing is : if you buff the Warrior set, you shouldn't change him into a beast and, due to the relative versatility of its tools, you should do the good choices.
I'll talk about what I think to be good to change.
Brawl is ok since he clean the board and can be used when you haven't got any creatures. The issue is that you probably need to allow the Warrior to use a little more Board Control when he doesn't have that card. Fix the mana cost at 6 and it shouldn't handicap the players who's using it, without making the capacity of Control being insane for the Warrior : 6 mana, because 5 allow you to put a too big creature, or 2, when 6 means that you'll do a smart choice.
Shield Slam is legendary. It cost 1 mana and do 1 damage by each armor point you have and it can be a great amount. The card is ok but, in some cases, you can imagine it better with a mana cost of 2 and the capacity to hit the ennemy character and not only minions.
Cleave should definitely do 3 damages and cost 4 mana like Multi-shot, because 2 isn't what you need to kill something that cause trouble... It's usefull when you don't need it : early game, but you already have tools to deal with early.
Whirlwind should do 2 damages to all. It should be the effect of a dying Abomination, and remember that it can affect your board too, so, that's probably not OP.
Shield Block can be changed for 2 mana cost and 3 armor.
Slam should do 1 damage to be ok.
That'll allow the Warrior to have a good Control of the board and reduce the amount of cards that he can play in a round (a part of his play-style, sure, but it's just not worth-it). He'll be able to draw a little more because he really need that to do his job.
The conclusion is : the Warrior is a very attracting class, it looks funny and powerful but it lack of Control to be. What he can do, other do much better. He have to specialize him in a way but if he do, he'll have severe trouble in an other hand.
