With the way the game is built you should never buy any warframe or weapon IMO. /QUOTE]
That's what I'd like to spend money on to support the devs but the prices mean I won't buy anything at the moment.
If they're wanting people to support them they shouldn't make things so expensive.
Fair enough mate, personally my opinion of the value of this game is the complete opposite.
People are getting 50, 150 and even more hours out of it, a tenner to get the most out of your time spent playing seems incredible value to me.
With regards to which starter frame to pick you can't go wrong with any, they're all great early to mid game and come end game you'll be using another frame and have several to chose from.
Loki with maxed out stealth is great solo and just as great in a group as you get huge cries murdering from stealth. Disarm has some superb uses in the more annoying grineer and corpus defense/survival missions. And decoy has massive use if used strategically with friends to attract and burn down piles of mobs.
Volt was a great choice, especially in corpus missions but he was removed as a choice in update 7 or 8 I think, long before PS4 launch. His parts did drop from J3 golem prior to update 11 and now they are a pig to get from missions, same as banshee.
Mag is fun, another solid choice for early to mid game and mid to end game you're useful in defense stuff to keep the objective safe, as a caster style character you're squishy compared to say Excalibur but stuff won't get close if you play well.
Excalibur is what everyone recommends, personally I didn't enjoy him at start or at 30 with everything maxed. Slash dashing around is fun, radial blind is useful in defense and radial javelin is nice and offensive and has good combos with Frost and Snow Globe.
If I was starting again today I'd go with Loki. If you make mistakes you will get murdered, but you can contribute to a good group and solo you can speed run parkour a lot of the objective missions.
