IMO, event cards should be fair to all teams. Event cards like this one are very unfair because some teams have amazing mono's, but some elements don't.
We are not going to totally ignore mono-decks because of the assumption that some elements have "amazing" monos while others lose with a mono every single time. The fact is that with a mono-deck that has the right cards, any element can beat any other element at any given time. Sure some elements might be stronger with a mono, but that's how Elements was built, and nobody is forcing you to use a mono-deck.
Mono-Darkness, Mono-Fire and Mono-Gravity are all very strong decks. Giving people massive amounts of upgrades for using these decks is just unbalancing the war. Yes, nobody is forcing you to go mono, but it gives a huge disadvantage to you if you don't.
Do these teams really deserve a second chance to come back and win when it is their fault that they lost?
Teams with less cards are already at a huge disadvantage because they have much less options in deckbuilding. Event Cards like these that could act as a small rubber-band, will help losing teams a bit by making their disadvantage smaller and making the event more fun for them because they still have a chance to win. But to say that round 8 Event Cards will somehow give losing teams an automatic win, is just dumb. It kind of reminds me of the time when everyone was saying that UW will auto-win War 4, and look what happened there.
Teams with less cards, have less cards for a reason at this stage in the war: Losing their games
What I am saying is that mabye giving too much help to the people who are losing in an atempt to even the field is pointless. War would, IMO, be better if the losers lost. You are also making the war longer, which is not what this war was meant to be.
I kind of regret implementing Event Cards in War in the first place. No matter what the cards are, it always leads to the vocal minority complaining about something, instead of just doing their best with what the organizers throw at them. I mean during this War, when though we have had the most interesting Event Cards yet, people still complain every single round. I guess complaining is a big part of the internet, but to me this has a very negative effect on the whole event and makes me question why we are wasting our time even developing these cards.
No. Scouting, General's Orders, Honour and Betrayal, Tortoise Formation and Enchanted Sword (Amoungst others I've probably forgotten) were all brilliant additions to the war. They were fair to all teams, and yet enhanced the war. I just ask that you think about how Event Cards will effect different teams and whether it is fair. On the other hand, if you think that the losers deserve rewards, then go with it; but next time: Justify your decisions.
