To give a descent answer. Instead of getting conquest rewards every 3 weeks, you get them now every 4 weeks. So far so good. But you need to see the whole picture and not only focus on conquest rewards.
Previous cycle was 3 weeks, ninja, conquest and war season. We now get ninja event rewards every 2 weeks, before this was every 3 weeks. Reasoning that way, should those rewards be lowered? Of course not, one reward is replaced by another one.
Sure, when you are in a high tier in conquest and win the rewards as a team, those rewards are more worth it for sure, in comparison with war season and ninja event. In terms of rewards, I would say be happy with the rewards you can win.
Community complained about conquest being too often. And for players who participate and need to be active a lot (like me) it indeed is very time demanding and exhausting. Would I want it to be similar like ninja event, every two weeks? Nope, not a single hair on my head is considering that. Even not when it would last just for 3 days, it’s too much and time demanding. Once every 4 weeks is fine with me and even every 8 weeks would be better, but once in 4 weeks I can live with.
The boost duration is a legal question, but also there, as long as you partially benefit from them during a ninja event for free, I don’t see a problem, when you want the conquest boosts for war season, you will need to prolong them anyway and same for war boosts, since both war season and conquest are now followed directly by a ninja event.
With war boosts it’s even worse, now you can get a specific set and you need to wait 8 weeks for that same set of war boosts. So a team really must spend gold to prolong them. I would suggest you better save that gold and level up the alliance or upgrade the alliance conquest buildings instead.
I am already happy to have the conquest/war boosts during next ninja event. And with 9-10 days that will last till next ninja event ends. Since prolonging those boosts cost a ton of alliance gold, it’s wise not to do so, unless you can afford it as team. But when there are alternate goals (Leveling up team, conquest buildings) I would invest the gold on that instead.
I think alliance gold we need for towers and research is fine. Lower would be better, but also realize we can gain huge rewards instead for all individual players plus the team. Take guardian chests for example, a lot of players can upgrade guardians. Take pal chests, we get a lot of pals and can donate them to the alliance (That we don’t use those higher level beasts is another discussion ?, but once you maxed a beast, your team gets 1M for every extra donated pal of that kind!). I can go on with pro chest and so on. Conquest is a team investment and in the end the team benefits from the invested gold.
I do understand the question, but please be happy with rewards we get. They are pretty good already. Need better ones, use my advice to upgrade team or conquest buildings and try to promote to higher tiers. Then those rewards will improve. Of course when you are already playing in top tier, then your rewards are already awesome.
