You say a few bad changes, but I can't believe you think things like sigils were an oversight, they obviously changed them in the hope no one knew and didn't realise why they were running out of energy.
They just over nerfed them and people caught them out. No accident.
I have sigils, yes I run out of energy, yes we had it one way and now it is different. My question to you and everyone complaining about sigils... why do you think energy sigils should work when a druid is healing? Isn't battle considered battle no matter if your doing damage or supporting? Health sigils don't work in battle, neither should energy sigils in my opinion. Just because your support and not doing damage doesn't remove you from the fact that you are " in a battle "
I will make the comparison to fuel in the UK,
When diesel was introduced, the government it cheap so everyone would buy diesel cars, now it is taxed the same as petol
When gas was introduced, it started cheap, now that there are a lot of gas cars, they are increasing the tax to push prices up.
Sigils worked really well, everyone bought them, then OTM had a lack of sales, so they make them work badly so everyone has to buy more. Simple economics.
Personally I think they are just annoyed at being caught out or they would have fixed them already.
And no, if you are healing, you are not fighting or being fought. They new that!
