We have as a goal to increase the reward up to 100%.
Why? To increase the inflation even more, and make the price lower?

What is the point in doing that?
Actually now masternodes do not earn much, as everything is taken by 2-3 people running huge number of masternodes... I am thinking about stopping my MN's, as they get almost no reward anymore... But increasing the reward for masternodes will not resolve this problem, as it will just de-valuate the coin.
It is much better to increase the amount needed for masternode at least 4-5 times! At least this will save MN running resources on VPS, and may justify running the MN...
The reward per block will not changed. But we want the limx is not only for multipools.
I don't think you will resolve the multipool problem (I mean the problem with blockchain stuck as a result of multipool activity) if you decrease the mining reward and increase MN reward.
The problem with multipools is because there is
not enough dedicated miners. If the hashrate created by dedicated miners will be big enough to correspond to the price, then multipools cannot do anything - they will just stop mining this coin (because it will be not profitable for them), and the problem will resolve itself. So you should do something to attract dedicated miners - for example increase the mining reward or just make more activity here and/or advertisement on MRR. If you decrease mining reward, the dedicated miners will drop, and the multipools will rule the coin..
MN is just a nice bonus to the coin, but the miners are of the biggest importance, they are moving the blockchain, so you should think of them first.
