I completely disagree about the 'skill' because most people who think there are skill involved are probably not playing at the highest levels.
Last week, I cruised through GW, I even got a DM that never killed me for 5 turns because I couldn't get my mana up on my cleanser.
I finished with the top score in my guild last week and am now the paragon.
So my first two battles today with the same team as last week went like this:
I start with a Herd/Kerb/Kraken/Abyssinia team and have a FULL mana herd master waiting for the DM and I kill the DK and all my troops get DMed, but it ended my turn. So next turn comes up and ALL FOUR of my troops died from DM in one go.
So I made a team of all impervious to counter this and was drowned out by not being able to get my mana together on my mana generator and the opponent had a funny thing happen, made a 3-match at the top of the screen and then three drops of skulls, giving him three attacks that took out my mana generator and I just slowly starved to death trying to output enough damage to win. Both cases were RNG eating my dinner and not giving me a chance to taste it. I'm a skilful player who spends time trying to figure out the best move each time and often, when the RNG isn't doing this, win win win.
The reason I'm complaining about keeping GW all RNG-based is that it really does serve that the luckiest guild gets to be on top each week if all guilds are just putting up grief teams.
I would prefer something that let us feel like skill actually mattered.
I'm fairly certain that all the people who post on the thread about how smug they are in their incredible skill just haven't had a run of bad RNG luck. As a person, I tend to get fairly unlucky when it's random chance so I'm terrible at gambling or similar.
I'm at the point where I'm starting to wish we could just push a roulette button and it would tell us if we won or lost our game rather than having to spend 10-15 minutes slowly taking moves to make sure I don't give away any points in GW.
