Support Breakpoint

Support Breakpoints are key levels that support units should be levelled to for useful passive buffs. Often new players believe Attack Power and such to be the key buffs here, but often the buffs gained are negligible. Instead buffs encouraging speed of stage clearing are generally prioritised:
 * Game Speed
 * Movement Speed
 * Attack Speed
 * Attack Range
 * Critical Chance (The one exception to the rule prioritising speed)
