Went back 10 pages and used search but didn't deem any thread worthy enough of my reply, so I made a new one
I get the feeling that the certification system in Planetside 2 is basically one you 'level up' or upgrade. So, let's say a Medic has 20 available certifications. You could, playing long enough, get every single one of those 20 certifications of the Medic. And thus be a fully functioning, buffed up, pimped up Medic and have every single and same ability as every other Medic, never less.
Opposed to 'specializing' your class, meaning if you go one route, you are unable to get certain other certifications of that class. So, for example, you could spec your Medic to be more combat orientated and miss out on some special 'Medic' certifications or you could go a Medic spec and miss out on some special 'Combat' certifications, no matter how many cert points you have left.
I prefer this last option, where you define a path for your Medic which is different from other Medics out there. Especially since they said there is no limit to the total cert points you can get, if you keep playing, you can 'get it all'. Basically meaning that all the true veterans will all be the same, they will have every cert and there will be no differences between them. No individualism or customization? No specialization?
Or am I wrong and do we already know that some certifications are mutually exclusive, if you choose one you cannot have the other?
