Main your Titan into pinnacle territory. After you have done this, move your highest light weapons to the next character, take the season pass armor bundle. 1 at a time and waiting for it to update light levels (as they increase as your light level does) , slowly open the rest of the seasonal armor from your pass. If you have it all unlocked (lvl 50 or so), you should be able to squeak your character to 1250 with minimal effort. Do not pump your alt characters to 1200 with silver, it's simply a waste of money for those that don't know better.
