Rivalries got bored for ace and nightmares

Rivalries got bored for ace and nightmares.
most of them going inactive now.
after death matches its too much down.

Better to change rivalry days from 7 to 4 and remaining 3 days death matches.
this sounds good for all....

almost my guild players leaving, not only them but so many guilds telling same...

Reason behind this is :
1.) Nothing after nightmare.
2.) nothing after full captaincy training
3.) nothing after getting their fav best weapons.

In My View:
1.) For Every 2 months captain Level should be increased some what with new strategies 31, after 2 months again 32, again after 2 months 33
2.) slowly infamy reset should be increased to 4100 after 1month 4200, there after 4300...slowly..which makes players happy too..
else every one thinking nothing after 4k and leaving.
3.) Bring new weapons.
4.) Bring all maps to Normal games...let us enjoy all maps not always large maps, small maps too... some thing quite interesting.
5.) Change season some what like this...
Challenger from 0 - 999 ( I - 1 to 333, II - 334 to 666, III - 667 to 999)
Warrior from 1000 - 1999 ( I - 1000 to 1333, II - 1334 to 1666, III - 1667 to 1999)
Master from 2000 - 2999 ( I - 2000 to 2333, II - 2334 to 2666, III - 2667 to 2999)
Ace from 3000 - 3999 ( I - 3000 to 3333, II - 3334 to 3666, III - 3667 to 3999)
Nightmare from 4000 - xxxx ( I - 4000 to 4333, II - 4334 to 4666, III - 4667 to 4999)

Due to changing like this some may feel loosing battle rewards bonus, so make some changes in that...
Encourage nightmares and ace people and make them not to leave game...
