Revinor, as a subscriber with similar initial concerns, let me say that this path does a great job with the combat encounters and, unlike a certain
WotC campaign arc currently being published, it also has likeable characters and a coherent storyline.
If you do go with the subscription, consider your players. If they are standard, every-day types, this path needs no adjustment. In my case, where I have players using the optimization boards at
WotC everyday to buff out their PC's, I found that I simply needed to add 1-2 extras in a given fight (the White Wyrms one described above had an extra bandit and an extra strorm wizard and it went smashingly). Also, Morrus and MerchantSteve are excellent at customer care; I've received PM's and suggestions on these boards in under 24 hours on how to bump up the difficulty in an easy way that takes no prep work for me.
My advice: Go for it! You won't regret it as this path is equipped for all playing styles and all degrees of player experience.
