A big collection will help in every mode, except LW. Just saying.
I was playing EFC with a cheap deck and decided to stand at 400 points, until weekly reward. So, it is possible. I had to be tricky though and play during DT hours. During eneven hours I got killed over and over again. This might even out when more new players arrive.
Yea they could make it were you get placed with better matches like 3 zones away in ether direction from the zone your in. but they have had a match making problume since the game was made its in the base code that would be a problume to change could destroy the hole game if done wrong.
I think etc is decent. It increases demand for old cards that used to be useless in addition to the new cards. In the long run that's good for the game.
In the short run, players will just need to adjust and adapt. Elo was a boring broken mode. Cards like leviatonn and methane weren't going anywhere. Now staff came up with a way to finally shake up those old staples but also give us all our old banned cards back. I think in time people will see the benefits of this mode.
Then that becomes stagnate an rather fast. an player in zone one would not have a challenge only facen zone 2 players.
think long run since efc runs for a month before given out the best stuff.
thats why i was thinking 3 zones away puts zone ones at least against zone 4 players puts some pressure. an i have notice players who love half decks the most zone 1-2 favor them very highly. casue the limitations on card. so efc balance all cards aloud up to zone 4 then it gets harder. then you down to half a clan so mix cone in. 3-2 gets chalanging even aginst op decks you have a challenge but can win with cards you never thought to use.
zone 1 the best of the best can win with the new cards aginst any deck they fight. a true skilled player.
*There should be max X rank difference between opponents you can face, like it was ELO.
For a low players who haven't experienced that themselves but will want to argue- people who are in top of EFC are often winning 9 games of 10 and still losing more rank for this one lose than all won games together. We want to play mode who we can enjoy not to play mode where one game will ruin all your evening you tried hard to get some rank.
*It should be enjoyment for the game not bigger and bigger prizes which are driving us to play this game.
