That means this.. helipad gives you some things "missile, propaganda, smoke, freeze, paratroopers, healing" ... and you need talents for that things.. not talents for energy gain, squad dmg, flaco dmg, flaco hp, gordo hp, gordo dmg, rpg dmg, rpg hp, armed truck and all ****** things you can get, squad hp or anything else.. You need talents for things that are in power of helipad. Especially missile damage. Because on higher levels, you will face up enemies with 20k bonus or even more on their rocket launcher, and you'll need to take those rocket launcher as soon as possible.. that can be done in 3 ways..
1st way = You play with Diegos, you chase talents for missile damage
2nd way = you play with Scorpions, or at least chase talents for firebomb damage
3rd way = if you don't have missiles strong enough, you might take talents for freeze. that means you don't have to take rocket launchers, you just freeze them as much as you can.. you can either go after them while they are under freeze, or trying attacking finca (but i wouldn't suggest you that)
