Firstly, if you have a pile of disposable income at your side, then by all means I recommend you grab this pack. It’s a decent starter pack, although with two rather lacklustre, and fairly rubbish planes (but they're Premium, allowing you to unlock planes at a faster rate). The 10K eagles is good value, and the two-month boost is a bonus.
Secondly, however, there are rumours that Gaijin Entertainment inflated the price of some of their buyable packs in the past during a Steam sale and discounted it back to the original price claiming it was on sale for cheap (The Mustang Pack). I can say from personal experience, it’s truth. It’s illegal in the majority of modern countries, and should not be tolerated. I do not recommend this pack to you if you have any sense of moral judgement. It's only supporting a rather corrupt development team.
